Re: IDLE: clearing the screen

OK, here is the advanced version:
import os
class _cls(object):
     def __repr__(self):
         os.system('cls')
         return ''
cls = _cls()
Now when you type
cls
it clears the screen.  The only flaw is that there is a blank line at the very top of the screen, and the ">>>" prompt appears on the SECOND line.
(This blank line is because the IDLE prints the blank value returned by "return ''" and adds a newline to it, as it does when printing the value of any expression.)
