Subject: [Chicago] pyodbc to ms access
Message-ID: <CAPrZ9u=o1Xc8ajuNhtwKn0+zjGCebF5v3bz3PT1xQmr=_c_P3A@mail.gmail.com>

Does anyone have some advice or insight on connecting to an MS Access
Database using python?

Here's my info:

Connection String:

    r'DRIVER={Microsoft Access Driver (*.mdb,
*.accdb)};DBQ=C:\Path\to\DB\db.mdb;'

Python Version:

    Python 3.5.1 :: Continuum Analytics, Inc. - 64 bit

OS

    Windows 7

Office

    32 Bit
Here's my error:
    Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source
name not found and no default driver specified (0) (SQLDriverConnect)')

but...

pyodbc.dataSources() returns:
    {'Excel Files': 'Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm,
*.xlsb)',
     'MS Access Database': 'Microsoft Access Driver (*.mdb, *.accdb)',
     'dBASE Files': 'Microsoft Access dBASE Driver (*.dbf, *.ndx, *.mdx)'}

Do I need to use a 32 bit python to get this done?
Can I specify the python bits version to use in a specific conda env?

Thanks,

Aaron

You probably need to exhume a "Jet" db file format parser. Take a deep
breath. Maybe there's ODBC, but probably not.

First, he is on the right path about the  32 bit vs 64 bit issue. Second, ms access is weak sauce and he should use a much more robust db with better python integration.

Noah and Pat

Thanks for the replies and confirming that I am on the correct track with
the 32 bit vs 64 bit version.

Looks like the 32 bit data source manager is buried in a sub folder and
doesn't launch from the control panel.  Thank you MS.

I'll move to a 32-bit version of python and try that.  This really should
not be harder than providing the correct connection string to either pyodbc
as Pat has demonstrated.

Also, I agree with comment on MS Access being weak sauce.  Unfortunately,
it's not my database, and that's where the data exists.

Thanks Again!

Good Morning Aaron,

The trick I've always used on ODBC connections in 64 bit windows is to
use the two ODBC administrator tools.

The 64-bit ODBC Windows admin tool can be found here:
C:\Windows\System32\odbcad32.exe   (If you are running 32-bit Windows,
this will be the only tool present, but then most of these issues
don't happen anyway.)

The 32-bit ODBC Windows admin tool can be found here:
C:\Windows\SysWOW64\odbcad32.exe

What will happen is that if you run a 32-bit application (i.e. MS
Access) it will look at the ODBC connections in that 2nd tool. If you
run a 64-bit application, it will look in the ODBC connections in the
1st tool.

I would suggest going into the 64-bit admin, setting up a connection
pointing to your Access db, and then calling the connection like all
other ODBC connections

cnxn = pyodbc.connect('DSN=<Name you used in creating ODBC connection
in the admin tool above>;Database=yyyyyyyy;UID=xxxxxxx)

Your 64-bit python should then work like normal. This will work well
so long as the location of that Access db doesn't change very often.

I feel like when you try to make the connection on the fly like in
your code below, that it isn't going to default to the correct
bit-version of the drivers. Hence setting it up explicitly in the ODBC
admin tools.

Rob

Here's my info:

Connection String:

    r'DRIVER={Microsoft Access Driver (*.mdb,
*.accdb)};DBQ=C:\Path\to\DB\db.mdb;'

Python Version:

    Python 3.5.1 :: Continuum Analytics, Inc. - 64 bit

OS

    Windows 7

Office

    32 Bit
Here's my error:
    Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source
name not found and no default driver specified (0) (SQLDriverConnect)')

but...

pyodbc.dataSources() returns:
    {'Excel Files': 'Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm,
*.xlsb)',
     'MS Access Database': 'Microsoft Access Driver (*.mdb, *.accdb)',
     'dBASE Files': 'Microsoft Access dBASE Driver (*.dbf, *.ndx, *.mdx)'}

Do I need to use a 32 bit python to get this done?
Can I specify the python bits version to use in a specific conda env?

Thanks,

Aaron

Good luck. Glad you found the folder (things like that lead to the "weakness" comment).... Seem to recall another work around, and if I find it I will let you know.

Rob, this looks like really good advice.

I got caught up in some other tasks today, but will try to verify your
solution tonight.

Is the yyyy in Database the path to the file?  Do I need so specify a User
ID for xxxx or can I drop that from the string?  There no specific UID
associated with the database.

Obviously, I'm a new to this.

Thanks,

Aaron

Five years ago I had to pull some data out of Access.  I don?t have the code available any more but I remember I used libraries that came with ActiveState?s Python.  I also remember it took some trial and error.  Eventually I got a nice flask + SQLServer site going to replace a buggy multi-user Access system that had grown too big.

There were a couple of ?recipes? in the second edition of the Python Cookbook that are outdated but still on-line (http://code.activestate.com/recipes/528868-extraction-and-manipulation-class-for-microsoft-ac/ and http://code.activestate.com/recipes/52267-reverse-engineer-ms-accessjet-databases/).  I found them useful as an example of navigating Access? data base.  The code itself is so out of date it wouldn?t run 5 years ago so I don?t hold out much hope for it now.

I?ve no experience with it but another route may be IronPython since access to Access is probably smoother from the .Net virtual machine.  Manning?s ?Iron Python in Action? I think covered ODBC and the sample code is available for download from http://www.ironpythoninaction.com/download.html.

I looked at microsofts documentation about exporting data from access.
Apparently you could export your Access database into an Excel spreadsheet
and then using Excel you could output to CSV and then you could load it
into pandas or python and then put it into a database. See
https://support.office.com/en-us/article/Export-data-to-Excel-64e974e6-ae43-4301-a53e-20463655b1a9

Hello!

I?d like to give a talk on managing technical debt in a Python-driven startup environment. I?ve met more than a few people at ChiPy who sound like they?re newish to Python and either interested or already in a startup environment (either within a larger corporation or an actual startup). Python makes a *great* tool for that, however there?s ways to use it to carry your work along to great success, and there?s ways to wind up with such spaghetti you?re tempted to throw your hands up in the air and go back to Java. The focus on the talk is how to use Python and the tools it provides to avoid the unmaintainable mess while still being able to ?cut corners? to get something out the door to make your boss/investors/customers happy.

THANKS for the help everyone.  I finally managed to get a working connect
to the access database.

Here's a quick summary for those following the thread.

1. Connect via ODBC using pyodbc library.
2. Setup a DSN using the ODBC manager located in
C:\Windows\SysWOW64\odbcad32.exe.
3. The 32-bit manager does not come up in the default windows manager found
in the control panel.
4. I have an *.mdb file and used the driver only labeled *.mdb (not
*.accdb, *mdb).
5. A 64-bit python *DOES NOT* work with the 32-bit access driver.
6. Using a 32-bit python resolved the issue.

Code for Connection:

>>> import pyodbc
>>> c = pyodbc.connect(r'DSN=my_db')
>>> crsr = c.cursor()
>>> for t in crsr.tables(tableType='TABLE'):print(t)
>>> c.close()

I also installed both the 2007 and 2010 redistributable drivers.

ChiPy,

Our May 12th meeting is upcoming, and we have some good talks planned.

This month, our first batch of ChiPy T-shirts will also be on sale for $15!

Join us at 6:00pm to hang out, network, and eat!

New ChiPy attendees are invited to stop by the "ChiPy Welcoming Table" at
6:30pm, where you can learn more about ChiPy and meet some new people.

The presentations will begin promptly at 7:00pm.

All are welcome! Please RSVP
<http://www.meetup.com/_ChiPy_/events/230731798/> soon.  Please provide
your full name in the RSVP for the security check at the door.

*When:*
Thursday May 12th

   - 6:00pm:  doors open; food arrives
   - 6:30pm - 6:45: ChiPy Welcoming Table open
   - 7:00pm:  Talks Start

*How:*
You can rsvp at chipy.org or via our Meetup
<http://www.meetup.com/_ChiPy_/> group.


*Where:*
Braintree
222 W Merchandise Mart Plaza <https://goo.gl/maps/Tb4AcPVJYwC2>
Suite 800
Chicago, IL

*What:*

   - *The 'collections' module*
   (0:10:00 Minutes)
   By: Phil Robare
   A quick overview of the collections module and its five data structures.
   The talk will be aimed at the intermediate level python user who has the
   basic syntax down but has not yet delved into the wealth of programming
   tools in the standard library.


   - *pyStan: Bayesian Inference for Fun and Profit*
   (0:30:00 Minutes)
   By: Stephen Hoover
   Probabilistic programming languages offer a flexible and expressive way
   to model data by treating random variables as first-class objects. Stan is
   a popular and well-supported library which allows users to write models in
   the Stan programming language and use MCMC methods to perform Bayesian
   inference. Stan itself is written in C++, and has a Python interface
   through the PyStan package. In this talk, I'll show off some of the
   capabilities of PyStan and go through a simple practical example of
   Bayesian inference in Python.


   - *Python, Startups, Tech Debt, and You*
   (0:20:00 Minutes)
   By: Matt Erickson
   There's a lot of people newish to Python and either interested or
   already in a startup environment (either within a larger corporation or an
   actual startup). Python makes a *great* tool for that, however while
   there?s ways to use it to carry your work along to great success, there?s
   ways to wind up with such spaghetti you?re tempted to throw your hands in
   the air and go back to Java. The focus on the talk is how to use Python and
   the tools it provides to avoid the unmaintainable mess while still being
   able to ?cut corners? to get something out the door to make your
   boss/investors/customers happy.


Thanks always to all our Platinum sponsors, especially: Braintree,
Imaginary Landscape, and Telnyx.

Please be aware of our code of conduct http://www.chipy.org/pages/conduct/

See you there!

Josh,

Sizes mostly range from small to XL. We have a few XXL. There is a limited
quantity available for all sizes for this first run as we gauge interest.
However, if sizes run out, I plan to take down names and get a second batch
going. Cash only for now.

Joe

Hey all:

yes the hype curve is flawed...

So here it is:  https://www.surveymonkey.com/r/python_hype_mailinglist

Please take the survey as I will also want to do a poster session on this
at Pycon.

After doing a lot of research I have a hypothesis of where the language is
at. I want to see if it lights up with the answers. Also, I am offering
dinner to a couple randomly selected folks who take it.

Cheers and Thanks for the Fish!

Subject: [Chicago] Handling secret stuff
Message-ID: <5737931E.6040001@mushroomthejournal.com>

Hi, everyone

Is there a "best practices" (or even a "minimally adequate practices") 
post/article somewhere for handling a secret API key?

My dilemma: customer interaction on client's website needs follow-up 
action that requires secret API key. Client insists that this must all 
be automatic and triggered by customer action. I'm like "Any chain of 
actions that is automatic and initiated by action on a public page is 
going to leave a trail to your key." I have a couple of potential 
solution architectures in mind (that are actually secure), but for now I 
mostly need to talk client down from this idea that it needs to all 
happen totally automatically and yet with complete security. Of course, 
if there *is* some magic architecture through which this can happen, I'm 
all ears. :-)

Thanks!

I'm not sure I understand your question. Take Braintree (where I work) for
example -- every time someone sends us their credit card info, we connect
to a credit card processor using a secret API key and send them the data.
How is that different from what you're describing?

Why wouldn't HTTPS / SSL be good enough to keep your secret data secret ?
That probably won't be easy to crack for at least 5 or 10 years ;)

@ my question of 4:05pm

I should also add that this is a WordPress site, so it's not a situation 
where I can do things with the server's system itself. :/

Leon,

If you're saying you'd need the secret key to be present client-side in the
customer's web browser, then no, that isn't secure.

You need a server-side component, or you need to get some sort of one-time
use, limited scope key that can only be used to take the action the
customer is permitted to take -- and whether or not that's possible depends
on what the API is you're interacting with.

Hmmm, yes, that could do it.

Just tell your clients they should pay you more.

We need a venue for June 9th.  Needs to hold about 120-130 comfortably.

We have some back up locations; however, before we resort to those wanted
to reach out and see if anyone has something in mind.

Please let myself or one of the organizers now.

Thanks!

Like Adam I am not sure of the constraints you are working under or exactly what you are trying to do.  So this is a guess at restating it.

You have a website running on a server whose security is questionable.

The user in their browser initiates an action that you wish to have ACID properties (Atomic, Consistent, Isolated, Durable) as well as CAINE properties (Confidentiality, Integrity, Authenticated, Non-Repudiation, Encrypted).  Throw enough bull stuff acronyms around and your client may be impressed enough to allow you to do things the right way.

You might try OWASP.org and the articles there.  If nothing else you may be able to collect enough examples of hacks to scare your client into acknowledging that the Internet really can be a scary place.  Another resource is RFC1825 which discusses Key Management and other architectures involved in creation of secure services of IP.

You also might think of architectures like what Adam referred to where the webserver passes the actual secure work off to another server with better security.  Typically the second server will only accept connections from the web server(s) it knows - which limits the attack surface exposed on your WordPress site.

Good luck with your attempt to educate your client.

Leon,
If you're saying you'd need the secret key to be present client-side in the customer's web browser, then no, that isn't secure.
You need a server-side component, or you need to get some sort of one-time use, limited scope key that can only be used to take the action the customer is permitted to take -- and whether or not that's possible depends on what the API is you're interacting with.

Dear Leon,
Also useful in justifying things to people who are managers and up is to
quantify how much money they would loose if their credentials were
compromised. That may get you better results in educating your client.

Thanks, Adam and Rob!

I'm not worried about transmission -- yes, we have an SSL certificate 
etc. My concern is with storage of the API key on the client's website.

The service provider in question does things a little differently from 
Braintree: it's a two-step process. The client has a secret API key that 
sort of serves as an authentication of last resort. The client sends 
financial data to service provider along with a public API key and the 
service provider sends back a one-time token that (hopefully) indicates 
that the proposed transaction has been checked out and can move forward. 
Client then returns that token along with the secret API key to service 
provider, and money then actually changes hands.

The client is running a temp agency, with work being done over distance. 
The proposed architecture is that the temps log in to clients website 
(which is Wordpress), fill out the amount they are charging the 
customer, etc, and hits a button initiating this complete back-and-forth 
process.

My concern is that if the whole process is automated and triggered by 
the temp hitting the button, this leaves a code trail to the secret API 
key. Sure, the page in question can be protected in various ways, but 
there's still a code trail that... well, if there's a programmatic 
sequence of steps that involves retrieving the key, those steps can also 
be traced by an outsider if they can get at the page somehow.

My thought was to have the temp's page merely log the information 
(including the returned token) from the temp's payment request into the 
Wp database (I'm not worried about the security of Wordpress). I would 
then have a completely separate scheduled process go through these log 
entries and complete the second part of the back-and-forth for all of 
them at once. That way, the sequence of programmed events that retrieves 
the key doesn't need to have any involvement with the public interface 
at all. This seems more secure to me -- no code trail. But I don't know 
what SOP is in this sort of situation -- or if there is any. Like I 
said, I don't know if there's any best practices here or what. Any help 
appreciated! :-)

Thanks!

What is this "code trail"? Every time you start up a session (among other
things) on a Django site it's automatically hitting the SECRET_KEY to build
a token for the user. Despite knowing that, the key, for all intents and
purposes, is safe.

Is your presumed attacker a malicious temp employee who has access to your
client? Are you exposing the key to the employee's client (ick), if not,
how does said employee get at it?

Generally what you'd do is make the signed API calls from the server (via
requests, or curl or whatever), and never, ever expose the private key to
the browser.

At that point, the key is only accessible by people who have access to the
server or the codebase.  For the latter, there's quite a few tricks for
keeping the key out of your repository; environment variables, separate
files, etc.  For the former, it's assumed that your sysadmins are
trustworthy!

Oh I see the other half of this thread.  Awkward, it will pretty much
always be insecure until you add a server that you/your client control.

The user of the site only gets to see the input and output of your code,
not the code itself. As long as you are careful with your inputs & outputs,
you won't be making any kind of "trail" to the secret key. I would
re-examine the "code trail" idea entirely, as I don't think it makes sense.

Hi, everyone

and thanks for the suggestions!

Thanks, Philip and Joshua. I have been reading OWASP and they are a big 
part of what scared *me* wrt this situation. :-)

Nick, I don't know how Django works. But @ the "code trail", Wordpress 
runs on php, which means that when you have a form on a page that's 
supposed to do stuff, the form says
<form action="complete_pathname/dosomething.php" method="post">
and the dosomething.php file is unencrypted text. If the that file 
contains or just is able to access the secret API key, I have a security 
problem. While a would-be hacker may not (shouldn't!) have permissions 
to get to that php file, they at least know where to look, or perhaps 
they can devise some method of triggering the form's actions and having 
its results directed to them. JavaScript has a similar problem -- any 
action you want a page to take is written down in unencrypted pages that 
are interpreted live. It sounds from what you're saying that Django has 
layers between the pages that it serves and code that it runs that make 
this not a problem.

In any case, this is the motivation behind my provisional idea of 
(something like) Japhy's solution -- I'm not running the host server, 
but at least perhaps I can trigger the more sensitive part of the 
operation by scheduled actions which are independent of anything that 
happens via a browser.

Thanks again. Your ideas help me think. :-)

This is a good discussion and I'm glad we're having it on this list.

Big thumbs up to everyone's well thought out responses.

Leon,

Please stop changing the subject of the thread, it makes it harder to
follow the conversation and clutters up peoples' inboxes.

You're mistaken about it being a security problem if "dosomething.php"
contains the secret key. If your web server is being configured correctly,
the user of the site can't actually see the contents of "dosomething.php".
The web server uses a PHP plugin to run "dosomething.php" as a program, and
then sends its output to the web browser. So the contents of that file are
secure -- anyone who has access to it already has access to the secret key.

Also, I?m guessing that PHP has some way to read in environment variables from the server its running on; this is typically the method used to secure API keys and the like on Django/Python web servers. Is this not an option for you?

While we're jumping on security bandwagons, if keys could be extracted from web servers with relative ease, SSL would be more broken than it already is.

I know practically nothing about PHP, but if your server is configured such
that users can view its source over HTTP, that sounds insane. Apache or
whatever shouldn't naively handle a request to a *.php URL. If you have PHP
questions, I'd ask that community, but some quick Googling:

Thanks, everybody

Looks like I was worried about something I didn't need to be worried about.

Message-ID: <CALz6jQjhAcdN7sJ1c7KB3b_FLLvtJgzBiUGfKDPfYjZQBHxA6g@mail.gmail.com>

We're growing the crowdSPRING team. We launched in 2008, re-launched a new
site in 2010, and are now working to make crowdSPRING even better by
reimagining *everything* about our business and our industry. This is a
unique opportunity to join a profitable company and a small, agile team.
Our office is in the West Loop.

crowdSPRING is changing the way entrepreneurs, startups, established
companies, agencies and non-profits around the world buy graphic design,
industrial design, and naming/writing services. Over 185,000 designers and
writers from nearly every country in the world work on crowdSPRING.

We're looking for two engineers: a senior full stack engineer (with strong
python experience) and a backend python engineer. [we're also looking for a
marketing manager - you'll see that description in the link that follows].

https://crowdspring.workable.com/

Want to build something amazing with us?

Best,

Ross

Thanks for pointing that out. I don't know if the Boston Python User Group
is keeping their materials there anymore.

I've been gathering info on my office hours wiki and would like to keep
things up to date and in trim shape.

https://wiki.pumpingstationone.org/Talk:Python_Office_Hours#help_find_new_and_better_guides

I don't think non ps1 members can edit there, so I'll figure out a better
way to get corrections/suggestions.

I'm between a L and a M. What's the consensus on how these fit/shrink?
Relaxed, or tight?

If your server takes the message from the user, bundles it in the same 
request body as the secret key, then transmits it over ssl to the 
provider's server, you run the risk of allowing a compression oracle attack.

The way to avoid this as a programmer is to ensure that the secret key 
and any user supplied data are not combined in the same request body. 
For HTTP compression it's sufficient to simply design the protocol so 
that the key is in a HTTP header field. This won't prevent creating an 
oracle if compression is used at the ssl level, but that's why ssl 
compression is deprecated.

They?re definitely on the tighter side, but not by stupid amounts. They?re American Apparel shirts, if you?re at all familiar with how they fit and shrink.

Joel Grus (author of O'Reilly's "Data Science from Scratch: First Principles with Python") has written a hilarious post about being asked to write FizzBuzz in a Python interview.  So he sets up a neural network.  Check out http://joelgrus.com/2016/05/23/fizz-buzz-in-tensorflow/

Of course, as one of the comments points out, if you have to do fizzbuzz in Java there is the Enterprise version of FizzBuzz with all the GoF patterns: https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpriseEdition.

I saw that on Hn . The funniest thing is that at the end the trained tensor
flow network doesn't even return the correct values after it is trained.

Well yes, that's the thing about probabilistic algorithms....

As an aside, we can all laugh at fizzbuzz, but you'd be shocked just how
brazen people are about their skills/accomplishments on a resume.

I mean, it's so quick to do fizz buzz, just give a cheeky list
comprehension and get on with life:

['fizz'*(x%3==0) + 'buzz'*(x%5==0) or x for x in range(1,100)]
I'm sure someone on this list can do an even simpler one with iterators.

I can't tell if you're trolling or not.

He should have written unit tests for his machine learning program?  On the
plus side, that's one the best definition of "results oriented" I've heard.

This is actually pretty interesting to think about.

1)  Are Tensorflow and related libraries actually probabilistic like I'm
assuming?  My uneducated abstraction is that they iterate over the data set
using some sort of randomization to create "rules" then apply them.
2)  If so, how do you test them?  Do you do multiple iterations of a test
and look at the distribution?
3)  How do you avoid "local minima", so to speak.  I saw a "step size"
reference in the article, is this how much the attempted algorithms change
each time?

Thanks!

Dear Irick,

To evaluate a model you would validate your model and one way to do that is
cross validation. First you need a dataset with the ground truth which
would be in this case the input (a number) and a string (a number or
Fizz,Buzz,FizzBuzz). You would test it by partitioning your dataset into a
training set and a test set and make sure that the model gets the right
answer for the test set (70% test set/ 30% training set is a frequently
used partition). When training the model sometimes you can get different
results so the model is probabilistic. You can avoid a local minima by
computing the derivative of the error function and selecting a step size
that will reach a minima and not either go past a minima (a step size of
too large) or never reach it (a step size of too small).
Sincerely,
Joshua herman

TensorFlow (and essentially every other computer program you're likely to
run into in practice) is totally deterministic, assuming that you set the
random seed beforehand. You can of course unit test each individual part of
tensorflow (or whatever ML library). For a system test, you could do
something like attempt to reproduce published results on simple data sets.
There are also tests that are specific to gradient descent algorithms, like
"gradient checking" (
http://ufldl.stanford.edu/tutorial/supervised/DebuggingGradientChecking/).

The question of local minima is actually pretty interesting, and is an
active area of research. Some research shows that local minima are not the
primary problem (http://arxiv.org/abs/1406.2572.pdf) or that local minimum
actually are equal to global minimums (under some assumptions,
https://arxiv.org/abs/1605.07110). See also
https://www.reddit.com/r/MachineLearning/comments/3hcijy/is_it_really_appropriate_to_use_a_gradientbased/
for
some more discussion on this topic.

Well, I thought it was more of a joke, but honestly, I can't even tell when I'm trolling these days.

The gist of it was "hey, if it's not working, test it more, and make it bigger for starters." At least that way you'll have a gigantic program that passes all the unit tests.

No one can argue with lines of code.

...This is the Java users group... Right..?

Subject: [Chicago] List comprehension question
Message-ID: <CABt5PSkL7E8-7gpXJbrVm83eXGGXupDf=GP8TpvfQueFOzm_-A@mail.gmail.com>

I've got a question about using list comprehensions.

I've got a piece of code that is making a MySQL query:
sql = "SELECT tail FROM aircraft_state WHERE airline='WN'"
c.execute(sql)

I'm currently using a loop to get the values into a list:
rows = c.fetchall()
for row in rows:
    comm = row[0]

since the return value from MySQL is delivered as tuples. I'd like to use a
list comprehension to build my final list (no important reason, I just want
to learn how). I tried:

comm = [x for x in c.fetchall()][0]

but that just gives me the first tuple. If I use:

comm = [s for x in c.fetchall()]

I end up with a list of tuples. Any suggestions as to how I could do this
without using a for loop?

move the 0 to the thing you want to 0...

comm = [x[0] for x in c.fetchall()]

I believe you want something like

comm = [row[0] for row in c.fetchall()]

Keep in mind that the list comprehension is going to evaluate that part
before the "for" for each row it gets from the cursor, so you need the [0]
inside there, not outside the list comprehension, which would be asking for
the first element from the list comprehension?not what you want.

Note that c.fetchall() fetches all rows, which might be a waste of memory
for large data sets.  Psycopg (PostgreSQL DB API library) lets you iterate
over a cursor directly:

comm = [row[0] for row in c]

*In theory* this doesn't have to load all the rows into memory at once.
 (In practice I bet it does unless you do something special with
Psycopg/PostgreSQL.)  I'm not sure if you can just iterate over a cursor
with your MySQL driver, but there's no harm in trying.

You did it! That's a list comprehension ?
It has a `for' in the syntax:

Very cool, thanks to both of you. That makes sense - I guess I'm just
suffering from temporary (I hope) brain fade.

You could potentially turn it into a generator comprehension (which might
ease the use of memory) with:
comm = (row[0] for row in c.fetchall())

Now that we have answered your question....

Stop doing all this and use an ORM.

manual way:
sql = "SELECT tail FROM aircraft_state WHERE airline='WN'"
c.execute(sql)
comm = [x[0] for x in c.fetchall()]
for c in comm:
    print( c )

ORMy way:

class Aircraft_state(models.Model):
    airline = models.CharField(max_length=2)
    tail  = models.CharField(max_length=20)

states = Aircraft_state.objects.filter( airline='WN'" )
for state in states:
    print( state.tail )


All of the SQL and stuff has been done in the models.Model class. This
includes generating and executing the CREATE TABLE commands to build a new
db, parametrizing the parameters so no SQL injection exploits or mistakes,
lazy reads so it ie less likely to read a bunch of data that never gets
used, etc.

And you write less code.  less code is easier to read and debug.

Sometimes an ORM is useful, but there are lots of cases where it can't do
what you want, or encourages tight coupling of your logic and data model --
which is bad when your data model has to change.

See https://github.com/kennethreitz/records for a nice wrapper around raw
SQL.

In my experience ORMs are good for the sort of simple filter and projection type of queries we have here.  And for those queries they can really help productivity as Carl points out.  As soon as you have the possibility of the SQL optimizer having multiple paths I have found the ORM just gets in the way of writing a good query.  Then the O in ORM stands for Obfuscation and you spend as much time figuring out how to present the query to the ORM as it takes to write the code in SQL.  And later maintainers can understand the SQL much more readily than the manipulations squirrelled away in the connector class can be understood.

On the other hand I have worked with people with years of experience in Django?s ORM or Psycopg and they could produce and maintain the ORM code quite efficiently.  The rest of the team,  with less experience, just had to take their word for it that this was the way to do it and not break anything.

Keep in mind that the list comprehension is going to evaluate that part before the "for" for each row it gets from the cursor, so you need the [0] inside there, not outside the list comprehension, which would be asking for the first element from the list comprehension?not what you want.

Note that c.fetchall() fetches all rows, which might be a waste of memory for large data sets.  Psycopg (PostgreSQL DB API library) lets you iterate over a cursor directly:

comm = [row[0] for row in c]

In theory this doesn't have to load all the rows into memory at once.  (In practice I bet it does unless you do something special with Psycopg/PostgreSQL.)  I'm not sure if you can just iterate over a cursor with your MySQL driver, but there's no harm in trying.

To add to the soup....

ORMs are the future, don't fight it.

First my resume:
hopefully you find this interesting.

I consider myself fluent in 6502 and 6809 assembly, when I looked at 8088,
80286 and 68000 I was not put off.  I have written C professionally and had
my patches to an open source C++ project accepted. From what I hear, it is
hard to write assembly code that is better than compiled C because the
compilers can do optimizations that are hard for a human, maybe because
brute force?

I am also fluent in SQL.  I have studied the SQL97 spec to try and figure
out what should happen when you ORDER BY with null's. (spoiler alert: it is
left up to the implementation.  I think this means they couldn't come to a
consensus and gave up.)  I have written frameworky code to construct SQL
commands, mostly WHERE clauses. I have studded the lex/yack syntax
definition files in hopes to parse SQL commands back into an object
representation so I could augment them.  (don't try to write your own
parser, you can only get 90% there, and it is the 10% that is hard and what
I needed to fiddle with anyway.)

I can also rant about Python's db-api spec and how parameter syntax is
another implementation detail which means everyone has to write a layer of
drivers to handle all the implementations of ? and {} and % and whatever
syntax the authors dream up. Gee thanks.

/resume

However, I kinda cringe at the idea of ever using those skills again.   I
much prefer Python over C, even if there are parts that would run faster if
I wrote them in C.  I suspect my Python version will be more maintainable
than anyone's C version.  This is because Python is a very well designed
implemented language.  Same with SQL.  Only once in the last 3 years have I
coded SQL:

(veyepar) carl at twist:~/src/veyepar$ ack-grep "\.raw\("
dj/main/views.py
1678:    raw_files=Raw_File.objects.raw(
1729:    episodes=Episode.objects.raw('select distinct e1.* from
main_episode e1, main_episode e2 where e1.id != e2.id and e1.start<e2.end
and e1.end>e2.start and e1.location_id=e2.location_id and e1.show_id=%s and
e2.show_id=%s order by e1.location_id, e1.start', [show.id,show.id])

(That first one is pretty much the same as the 2nd one)

I did that because I couldn't figure out the ORM code to do it.
(If someone can give me the ORM code to do that, I'll be happy to give it a
whirl.)

This is in an app with a bunch of views and stuff:
(veyepar) carl at twist:~/src/veyepar$ grep "^def " dj/main/views.py |wc
     49     139    1901

I think ORMs are currently pretty good but will get better over the next
decade.  Maybe something new will take their place, but it will be some
abstraction or whatever that is easier to work with than SQL.  ORMs kinda
struggle to work well with NoSQL db. They work, but I think they restrict
things to the point of losing most of the benefits of NoSQL.  (I guess.  I
have only made videos of such things, never got my hands dirty.)

So...

There are some good augments against using an ORM, but I think they are the
way to go right from the start.  Like me, you may need something they can't
do and you are forced to code SQL, but make that the exception not the norm.

You rank the languages that you used (if any) during that time frame. If
you primary used Python, that is 1. And if you also used C++, but to a
lesser degree then that is 2.

I have put the files from my May 12th meeting talk on the Collections module up on github: https://github.com/verisimilidude/TheCollectionsModule

The one exception is the data file I used, the City of Chicago's building permits data.  I have a file in the archive about how to download that data.

That's really educational for a self-taught sloppy python programmer.
Thank you very much.

Subject: [Chicago] PyData Chicago: Talk submission open!
Message-ID: <CACqadXo=4-D1coZ_SLn0sk2G1AYH0oUgfmc1gfBkNUoSRzM7Ew@mail.gmail.com>

The PyData conference is coming to Chicago this summer! The conference will
be August 26-28th at the University of Illinois at Chicago. The conference
brings together analysts, scientists, developers, engineers, architects and
others from the data science community to discuss new techniques and tools
for management, analytics and visualization of data. Presentations focus on
tools in Python and other languages used in data science, such as R and
Julia. The call for talk proposals is open now, and will close on Monday,
June 13th. http://pydata.org/chicago2016/cfp/

PyData is a great conference series, and I'm excited to have it come to
Chicago. Please submit talks, and mark your calendars! Feel free to contact
me with any questions. The conference also still has opportunities for
sponsorship available, so contact me if your organization might be
interested in sponsoring.

Stephen
