Python IDLE is not starting on Windows 7

Question

I used to use Python 2.7 and then IDLE was working. I uninstalled it and installed Python 3.1.
Right now Idle cannot launch. What should i do to get it running?

NOTE

Answer 1

Delete the .idlerc directory as suggested above, run the python installer again and choose repair. If needed associate the .py files with the python.exe executable in Python27 folder. This worked for me after removing python 3.7.
