The string module is deprecated but (most of) its features are now 
found as methods of string objects. However these are not always
enough fopr all tasks and thats where regex comes in.

In my own programming I probably only use a Python regex once 
or twice a month, but in Awk I use them at least every week... So 
if you use python for the kind of things I do in awk then you will 
use them much more often...

My tutor has a basic intro to regex, and there is a more 
detailed HowTo online linked from the python site.
