Clear Clipboard?
Question: Is it possible for python to clear the clipboard? If so ... how can I do it?

I need this so in my quiz program, students can't copy paste answers from the
internet and other files.

**EDIT:** Im using WinXP and Python 2.6


Answer: 
    from ctypes import windll
    if windll.user32.OpenClipboard(None):
        windll.user32.EmptyClipboard()
        windll.user32.CloseClipboard()
    

No external libraries needed.
