Thanks again for your thoughts Javier.
You've certainly given me a mouthful to chew on :~) I was thinking
more in terms of "OOP is about code reuse" and trying to equate the
function approach to such with the class methods approach in a
similar way. Obviously I have got my mind wrapped aro

In my original post I noted my recent exposure to Python and put up a
little utility to my iDisk asking for a Pythonese/Efficiency/
Generalese critique.

were greatly appreciated. To follow through with the learning

Hi Raywood1,
You have a few options. You may want to see if just turning the Tutor

Well, to make a long story short, this is because I use Python through
another software, Softimage|XSI, and by design a string is required to
pass logic to on-the-fly GUIs. Since XSI implements 3 other languages
(ActivePerl, VBScript and JScript), I suppose this was designed that way

It's worth noting that backticks are going out of fashion --- I think they are

There is a module for doing black magic like that. I think it may
be the one with the disassembler in it?

THere are several ways of using repr, the most common is at the >>>
prompt.
>>> x = 5
>>> x
5

when I typed x at the >>> prompt Python called repr(x) to display the
result. This can be slightly different to using print

Ok thanks a lot.
The real question is, then, is there a way I can print the code of a
function as a string? Something like
'def myFunction: print "hello"'
Thanks

In the first example, your repr invocation is:
repr(myFunc)
i.e., you're asking for the repr of the function myFunc.
In the second example, your repr invocation is:

Hi Bernard,
Ok, what do you expect to see instead of 'None'? I ask this to make sure
I understand the situation better.
Best of wishes?

That's perfectly normal. Your last assignment calls the
function, then assigns to s the representation of the functi
Hello,
Possibly I am missing something, but how do you use the repr() function?
I type this ultra-simple function:
def myFunc(): print 'hello'
Then run
repr( myFunc )
Wich returns

Okay then I run
s = repr( myFunc() )
print s
Wich returns
'None'
Thanks

How big are your lists (X and Y)?
A few minor suggestions below.

Hi,
I am wondering if there is a way to efficiently run a double loop in
Python. To be more precise, I would like to compute the sum of a
function f(x,y) for every possible (x,y) pair.
I have tried several alternatives so far:
1) the classic double loop:
for x in X:
for y in Y:

Just replying to myself because I am extremely dumb, so maybe it will

I forgot to include argv[1], which is basically the same as the name of
the file to be run.
So:
