Thus should be a FAQ somewhere...

Clearing the screen is terminal specific so Python doesn't have a single way 
to do it.
Since you mention Windows I'll assume thats what you are using and suggest 
you
simply use the CLS command via an os.system() call:

import os
os.system('CLS')

If you have Linux substitute 'clear' for CLS

Or as a last resort write your own:

 def cls(rows=100):
     for row in rows: print

If you use curses it has a couple of functions for clearing a window.

HTH,
