I am just starting on Python 2.6.2 on Ubuntu 9.04 and I am slightly
confused with the numerous tutorials and books available for learning
the language. Is there any good recommendation for a good but easy
tutorial on the Internet to learn Python?

Hi,
I am using the following code to check for the Python version -
import os
t = os.sys.version_info[0:2]
if (t[0] + t[1]) < 6:
os.sys.exit("Need at least Python 2.4")
del t
This snippet is put at the beginning of the single script file before
the rest of the code.
I need to check for the
As someone who learned (about) programming by copying and pasting code,
I really appreciate," Python for software design - how to think like a
computer scientist" by Allen Downey. It really talks you through the
workflow of programming, rather than just give you a long list of things

Not quite. What happens when you compare '2.4' and '2.10'?

Hi everyone,
I was wondering if anyone could offer advice as I try to simplify a
project I've been working on.
I have a set of classes that I've named models.py (following the
Django convention, though it's not technically a Django project or
app).
Inside that file, I had initially grouped toget

I'm now fairly familiar with Python, so I'm thinking about starting to learn
a second programming language. The problem is, I don't know which to learn.
I want a language that will be good for me to learn, but is not so different
from python that I will be totally confused. I tried learning C++ and

I recently started dabbling with Java, which has some great texts on

with Python).

Good for you in what way? Is there a general "good for you" for programming,
or do you need to achieve a certain goal? From a jobs point of view, Java
seems prett
Thanks all for the informative discussion. To re-confirm it was mostly

I have no real need to learn anything for a job, it's just a hobby right
now. I mostly just want "a programming language that has a different

Python". However, you guys are right, if I just learn a language without a
reason, it will be worthless.

Well, it's admirable that you're wiling to stick with it and learn
something new.
One other resource that I've personally been meaning to look into but

"ground up.

In that case consider Lisp (probably via Scheme) or SmallTalk.
Both are apparemtly different to Python but on

Ok, thanks alot everybody. I think I'll start with either Scheme or C, I
