Subject: [BangPypers] Does Python have lexical scoping?
Message-ID: <8761epq7u8.fsf@nibrahim.net.in>


Okay, I've been struggling through the proglang course on coursera and
this thing came up

   val x = 2;
   fun f y = x + y;

The second line creates a function that adds `x` to it's argument. Since
ML is statically scoped, this is really a function that adds 2 to its
argument.  Even if I later create a new binding for x later like so

   val x = 10;
   f (3);

I will still get back 5 (i.e. 2 + 3) instead of 13 (10 + 3). This makes
sense to me as an example of lexical scoping. The bindings are at the
time of definition rather than invocation.

With python, it's different. The claim is that it has lexical scoping
but. 

     x = 2
     def f(y): return x + y
     
     x = 10 
     f(3)

The answer is, distressingly, 13. The explanation was that although
Python has lexical scoping, that closure "close over variables rather
than values". Meaning that the variables (and not their values) at
definition time are stored in the closure. This is how elisp does it
which claims to be, by default, dynamically scoped.

(setq m 5)
(defun test (x)
  (+ x m))

(test 3) ; -> 8
(setq m 15)
(test 3) ; -> 18


So, my question is, how different is this from dynamic scoping (like in
elisp) where the values are actually picked up from the execution
(rather than definition) environment. This business of "closes over
variables rather than values" sounds like a cop out.

Comments?

I'll try to explain a bit, have to admit though, even my understanding
is not all that clear, and all is open for further discussion.

Here, technically ML's val bindings are actually immutable. When you
actually do a val x = 10; you're creating a new binding for x *shadowing*
the previous binding. Something like

fun f y = x + y;

creates a closure with f, and the free variable x.The closure locks
the function with the environment the function was defined in, locking x
to 2, as variables are always looked up in the dynamic environment they
are defined in before they are called, x is bound to 2. Also ML will not
allow you to define a function with x not previously defined, (ie no
forward lookups)

Here x was a mutable variable, doing a similiar ML construct, ie

     val x = ref 2
     fun f y = !x + 2

     f 10 ; evals to 12
     x := 10
     f 10 ; evals to 20

So this becomes a problem of closures over mutable variables? ie every
closure looks up the value of same variable, x which gets mutated
around. WDYT?

[...]

So the explanation I got is that it binds the environment at definition
time but the environment means a mutable table of key value pairs. In
other words, the closure closes only over the name of the variable and
not the value at definition time. I don't really understand how useful
this is unless you have some kind of environment that you can't get to
(e.g. non local inside a function etc.). Also, and this is my real
question,

How is lexical scoping with a mutable environment different from dynamic
scoping?

Here's my 0.0002 BTC; trying to reason from first principles:

Context:
In SML (and perhaps all strongly "functional" PLs), all values are
immutable by default.

Re-stating facts:
Now, any function in SML is just a value (that can be passed around).
This value is, semantically, a "closure" that consists of (A) the
function definition and (B) the environment that was current at the
time it was defined. This closure, though somewhat
"special"--semantically a pair of (A) and (B)--is really designed to
be just a value.

Intuition:
If the PL is to guarantee the immutability of this function closure,
then _both_ (A) and (B) must be guaranteed immutable as well.

Re: Python semantics:
I'm not terribly familiar with Python semantics. But I think if
values/variables are mutable by default, then the function closure's
"contract" differs from to SML exactly the way Noufal describes it...
i.e. the closure _cannot_ close over values, it can only close over
variables defined within the lexical scope of a function.

Contrast with a mutable SML variant:
I think if I defined 'x' as a mutable ref in SML and reassigned some
other value to it (set-bang), I can violate the function closure
contract.

Re: Dynamic scope:
AFAIK, this goes one step beyond (behind?) mutable variables. Even if
*we* don't mutate the value of symbol 'x', another process is free to
inject some identically named symbol 'x' into our current environment,
just in time to mess with the wiring of an otherwise sane function.

Hopefully I'm making sense.

I think you should post this in python-dev and you might get answers with
rigorous definitions.

Here is my short snippet which shows a behavior which does not indicate a
dynamic binding nature.


# example.py
x = 10
y = lambda: x

def f():
    x = 20  # This is not rebinding. It is creating a new local variable by
name x
            # But we are referring to x in y function call, so for the
definition of dynamic binding (?)
            # should y() see x defined in the local scope instead of the
previously assigned value.
    print(y())
    return y()

x = 30  # This is rebinding in the same scope.
print(f())

$ python example.py

Just for understanding, trying the same snippet in emacs lisp which has
dynamic binding will reveal the value of `x' as 20, as expected in
dynamic binding as we change the value of x inside the function.

(setq x 10)
(defun y () x)

(defun f () (setq x 20) (print (y)) (y))
(print (f)) ; 20 20

There are cases where both lexical scope and dynamic scope produce same
results. The example that you gave falls into that category.

Try the following example:

(setq x 5)
(defun getx () x)
(getx)

(defun f (x) (getx))

(f 10)
(setq x 4)
(f 10)

The function getx takes the values of x that is closest to in the stack,
not the one that is lexically closest.

Another example to demonstrate that.

(defun g (x) (h x))
(defun h (y) (getx))
(g 3)

With lexical scoping a can be resolved at the time of declaring the
function it self (as in name x in getx is alias to x defined in the
top-level), where as with dynamic scoping it can only be determined at the
run time. Because of this lexical scoping is usually faster.

prints 10, the x from function f, not global x.

prints 10 again. changing the global x don't have any affect.

Python or scheme (lexical scoping) would produce 4 in this case.

?Hi pals,
I need littele help ..
I made a program as per the given discription in the problem
but when I submit it , Spoj is not accepting it .
Can anyone tell me where I am doing wrong !

here is the problem set:
http://www.spoj.com/problems/PALIN/


and here is my solution:
??N=int(raw_input())
if N>0:
    for i in range(0,N):
        IN=(raw_input())
        if(int(IN)>=0 and int(IN)<1000000):

                while(True):
                    IN=int(IN)+1
                    IN=str(IN)
                    RIN=reversed(IN)
                    if(list(IN)==list(RIN)):
                        print IN
                        break

Hi Avinash,

I'd like to point out that the problem statement says that the given
integer K has at max 10 ^ 6 digits.
This does not mean that K is bounded by 10 ^ 6 !

Someone else correct me if I'm wrong, but I don't think this approach
will hold for such large inputs.

Kishor Bhat

I see 2 potential problems.
2nd raw_input is surrounded by (), is it correct?

In if condition conversion to list is not required. Also instead of
converting to string u can take difference of number and reversed number.

U can use tools like http://www.pythontutor.com/visualize.html#mode=edit
For better understanding of logic.

Hi Kishor,
10^6 is upper limit n is not a huge value. Memory footprint won't be high
because we need to find only next palindrome number. Or if required for
loop should be replaced with incremental while loop.

Let me know ur thoughts.

Nikhil

Hi Nikhil,

10 ^ 6 is the maximum number of digits, not the maximum number.

In this solution, you're going to start from K and increment by one,
checking at each stage whether ' n == rev(n)', which is a linear
operation.

Ultimately, this solution will be O(n ^ 2).

A better approach might be to modify the input number directly (by
manipulating the digits).

Also, the extra parentheses around the second raw_input() is not
necessary, but causes no errors.

Regards,
Kishor Bhat

my bad. I'm wrong at many levels.
Yes you are correct, for very large input it will be O(n^2).

This is a very basic question. You should go probably go through a
python tutorial before attempting this. I'm presuming that you actually
want to do something with opencv. If you don't understand the basics of
importing modules, you'll keep hitting roadblocks.

Your error says you don't have opencv python bindings or python can't find
the bindings. The command you showed, however, tells me that you have
opencv installed. Those 2 are different.

$ apt-cache search opencv | grep python
python-opencv - Python bindings for the computer vision library

I think your code imports OpenCV module and seems to be that it was not
properly imported or the module is completely missing. Please check into
that and try installing the module if missing.

Hi,

This is regarding diversity group organized by PSSI.

I have been actively volunteering for PyCon India from past 3 years and I
see the female python developers participation getting reduced year by
year. This was one of the concern PSSI had discussed during the AGM.

PSSI has come up with the initiative, diversity, where we all female
developers can share and discuss to see how we can improve the active
participation from female developers. If we have any concerns/expectations,
PSSI can help us the way they can.

We have the mailing list (
http://lists.pssi.org.in/mailman/listinfo/diversity) created. This mailing
list only for female pythonistas and the archives are not public so the
discussions are kept private.

I would request all female developers to join in the mailing list and share
your thoughts.
Please spread the word.


Thanks,
Vanitha

There is a Python diversity list at
https://mail.python.org/mailman/listinfo/diversity which you might want
to send your email to. There are folks from there from India and other
countries who are interested and will probably be able to contribute.

It's really good to see you taking active steps. From what I've seen in
last 4 years, I'd say this was very much necessary.

This is a new movement for a lot of the people in our community. So to
anyone who's thinking that they don't get it or this is separating the
community and hence is bad, I'd like you to read this blog post[1] by
Hynek Schlawack and the section with the heading "Why Women Only?"
here[2]. Maybe it'll help.

Thanks,
Bibhas

Are you a python developer who wishes to work with the latest cloud
technology? Do unfixed bugs keep you up at night? Do you want to learn more
about OpenStack and write software that may run on some of the biggest
clusters and platforms on this planet? Are you looking to be different than
the usual, run of the mill 9 to 5 mass recruited IT professionals?

If you answered "Yes" to most of the questions above, we should talk.
Because you are exactly the kind of candidate we are looking to talk to.

Aptira is one of the hottest startups in the cloud scene in Asia-Pacific.
We are well known in the community for being positively disruptive. Aptira
is a Gold Member of the OpenStack Foundation, and you will also have the
opportunity to raise your own profile in the OpenStack community.

You will do challenging work with an international, young and dynamic team.
You will work in a result and goal oriented environment, where the minutiae
of a normal corporate job will  never bother you.

Positions available for good programmers of all experience levels

Requirements:
- Good to indepth Knowledge of Python programming, some exposure to cloud
technologies would be welcome. Knowledge of OpenStack would be highly
desirable but not essential.
- Knowledge of CI/CD frameworks desirable but not essential.
- We work in an international team overlapping several time zones. We may
sometimes require you to work odd hours to solve a problem. Flexibility is
essential for this role.
- Ability to learn and adapt quickly to new technologies and opportunities
- Freshers welcome to apply

What we offer:
- Flexibility. Most of the time you can work when you like, where you like,
so long as we know what you're up to and you deliver on time.
- All about the improvement. If Agile taught us one thing, it?s
that we're never really good enough.
 - Our remuneration packages are pretty damn good, we send big teams to
conferences, and stuff.
- Training on OpenStack will be provided
- Commit directly to the OpenStack codebase and elevate your profile

If you think you fit the bill and are up to the task, drop me an email with
your resume and we would love to get the conversation started.

regards,

Kavit

Hi Sriram,

I had a look on task queues but don't think that was for my issue. I ended
up taking Anand's suggestion of making asynchronous requests using
Appengine's urlfetch (
https://cloud.google.com/appengine/docs/python/urlfetch/asynchronousrequests
).

Thanks for your help.

Thanks & Regards

Hi,

img=cv2.imread('4.jpg',0)
cv2.imshow('image',img)
k=cv2.waitKey(0)
if k == 27:
    cv2.destroyAllWindows()

elif k == ord('S'):
    cv2.imwrite('image.png',img)
    cv2.destroyAllWindows()

when I run this code,it is not possible to close the image window by
pressing esc key,and if going to close by using mouse the window will hang.
