FWIW, and while there of course are quite a few common rules (consistent 
and meaningfull naming, modularization with high cohesion and low 
coupling, "don't repeat yourself" etc), "good programming practises" 
greatly vary from language to language. In fact, one of the common rules 
is probably : "be idiomatic" - that is, don't try to write Pascal in 
Lisp (or C in Python...).

Indeed.

I second Steven's suggestion to spend some time going thru introductory 
material. IMHO, the official Python tutorial (to get the basics - no pun 
intended) and then DiveIntoPython (to see the language in action) should 
do.

Then you'll find that most people here will be very happy to help you 
rewrite your code in the most pythonic way if you kindly ask for help...

> Thank you for your help, all of you.
