I like that you can spell that
if 1 <= number <= 10:
in Python.

Hi all,
I want to build a small download accelerator program. I want to know how to
split the file to be downloaded into small pieces and assign the each small
piece to a thread for downloading.

Hello,
My code is -
l = len(m)
item = str(m[1])
for i in range(2,l):
item = item + "-" + str(m[i])
This code is part of a bigger function. It works fine. But I am not happy
with the way I have written it. I think there is a better (Pythonic) way to
rewrite it.
If anyone knows how to improve

OK, so what else have you tried and what are you h

(1) It is a matter of good programming practice. If you don't close them
yourself, Python will eventually close them
Hi All,
I had a question regarding installing packages that I posted a couple

output so that it is clearer.
I am unable to install libraries using 'python setup.py install'
Say that I'm installing a package "kando". I extr

I don't get it. If you don't close input and output it works exactly

I should add that this is the shortest, safest (as in "hard to get wrong")
and most readable way to open and close a file. It's worth getting used to.
