Subject: [Python Wpg] Next meeting reminder
Message-ID: <1182526980.3565.23.camel@localhost.localdomain>
Just a reminder that the next meeting of the Winnipeg Python Users Group
is going to be held at room 2M70, University of Winnipeg at 7:30 PM next
Wednesday (June 27th).
This meeting's topic is "Batteries Included: A Tour of the Python
Library" and we need your help!! If you'd like to give a short (10 or 15
minute) presentation on one or two standard library modules, please sign
up by editing the Presenter Sign Up page:
http://wiki.python.org/moin/PresenterSignUp
or reply to the list with the module you intend to cover. Remember, it
doesn't have to be fancy, just a basic run-through of the module's use.
So far, only Jason Hildebrand and myself have signed up to give
presentations. Come on, pythonistas! There's lots more library to cover!
Directions:
Room 2M70 is on the second floor of the University in Manitoba Hall.
>From the main doors in Centennial Hall, go up the escalator one floor,
take the first right through the archway into Manitoba Hall, then turn
left and proceed down the corridor. 2M70 will be on your right about 1/3
of the way down the corridor.

See you there!

Hi,
I have previously posted on Craigslist for a python programmer but didn't
get much of a response. Therefore I thought I might scare up some more
people on this list. My apologies to anyone who thinks this isn't an
appropriate place to post for a Python programmer.
I am looking for someone that is proficient in python and web development
technologies such as xhtml, css, and javascript. You should have a good
grasp of object oriented design and some understanding of HTTP. You will be
revising an already completed web application that is built atop a python
web development framework similar to Django (it is an in-house framework
that I intend to release as open source once it is mature enough to avoid
ridicule!) The code needs to be ported due to changes in the underlying
framework and the fairly inefficient way that it was originally coded. You
will have to change a number of pages from some very old crufty nested
tables to css driven layout.
If you are interested please reply to me personally at kevin at
rootsmith.cawith your experience and expected compensation. There is
somewhere between
one and two months worth of work.
Cheers

Hi folks,
It's great to see that several others have signed up for presenting on Batteries Included.
I was really looking forward to presenting on a couple of modules and learning about others, but some things have piled up on me and I won't be able to attend after all.
Sorry to have to back out on this.
peace,
Jason

Subject: [Python Wpg] Tested seed()
Message-ID: <46834181.2000303@gmail.com>
Here is some code.
#!/usr/bin/python
from random import seed, randint
seed(2)
for c in range(10):
print c,randint(1,10)
Ran it twice under idle and the same results came out three times.
Looks like it is best to run it without a value in seed().
Here is what I got...
IDLE 1.2.1
>>> ================================ RESTART
================================
>>>
0 10
1 10
2 1
3 1
4 9

You shouldn't pass a static value to a random seed generator. Pass
something that will change, such as the current time, or date, or ...
anything not-constant.

We had a discussion about this at the meeting. If you leave out the "2"
the seed is based on the system time. I was curious if putting a
constant in the seed() function would return the same values each time
it's run. Nobody knew for sure. Nobody caught anything in the
documentation. Now we know.
Historically there are only two random generators I've seen which "self
seed". The first is the Apple// (which I discussed at the meeting) and
the second is an *old* PC card which got its seed from the amount of
static electricity in the air.

If you pass nothing, i.e. just write seed(), it automatically uses system time.

Hmm... in the stock 2.4 python distribution, the random module is source code,
which is always fun to look at. :-)
It seems that seed() will use os.urandom(), if available, and will fallback to
time.time() if that's not around. It also seems like the module bootstraps
itself with a class instance, which is how the module does self-seeding...
which is almost always what you want (i.e., don't call seed(), it's already
been done for you). A reason you may want to call seed is: if you are
developing a program that relies on randomly influenced (but still
complicated) choices, and you wished to debug the non-random portion of the
logic... In my experience, seed( 2 ) and the like will ALWAYS produce the
same sequence of pseudo-random numbers, which is useful for testing
(sometimes), be it in Pascal, C++ or Python.

Hi,
When doing simulations it is important that you use the same seed in order
to acurately compare different alternatives.

Subject: [Python Wpg] Puzzled by traceback and pdb behaviour
Message-ID: <1183155149.14463.12.camel@localhost.localdomain>
Hi all!
I'm wondering if anyone has seen this and has a clue why it happens:
I'm debugging some errors in a ZopeTestCase test that I wrote, and in
the traceback that occurs (as well as in the interactive debugger), the
output lists a directory which was previously deleted, i.e.:
File
"/home/sweidman/Data/plone-2.5.2-instance/Products/CMFQuickInstallerTool/QuickInstallerTool.py", line 322, in installProduct
the directory "plone-2.5.2-instance" was deleted long ago. During
interactive debugging using emacs, emacs cannot find some source files
because pdb tells emacs to look for the file in the non-existent
directory. Does anyone know why this occurs? Should I try removing some
relevant *.pyc files?
Thanks in advance for any thoughts on this.
Have a great Canada Day weekend!
