I doubt the problem is your Python installation. More than likely it's
an IDLE bug. Reinstalling doesn't touch the .idlerc config directory
in your profile. Try deleting it if it exists.

If that doesn't work, run IDLE from the console so you can see if it
prints an error. Open a 'command prompt' and run the following:

    PYTHONHOME\Lib\idlelib\idle.py

Replace "PYTHONHOME" with the directory where Python is installed.

Run -> Run Module

That's just for testing in IDLE, which isn't the normal way to run
Python programs. Run your .py scripts (console user interface) and
.pyw scripts (graphical user interface) directly from the desktop
shell (explorer.exe) or the console shell (cmd.exe). For console
applications, running via cmd is better because you inherit the
existing console that stays open when your program exits.
