That should run the file and discard the output. Above is typical

*Something* very specific to your system changed. Either registry 
associations for .py are screwed, or your Python installation is 
damaged. Easiest fix is to uninstall and re-install Python. But download 
a more recent version first. Uninstall might not be needed, but makes 
process more like to work.

In the regular interactive command prompt interpreter

import idlelib.idle

should start idle.
