This is why I have a startup.py file that contains (among other things):

import sys, os


I'm not sure how you set environment variables under Windows, but under 
Linux I put this in my .bashrc file:

export PYTHONSTARTUP=/home/steve/python/utilities/startup.py

and whenever I start an interactive session, I get the common imports 
that I want, a custom prompt (I use 'py>' rather than '>>>') and 
assorted other goodies.
