I'm learning python on x64 windows 7 machine. But after installing and uninstalling python 2.7 and 3.2 a few times too many (i just found out 3.x doesn't support some of the 3rd party libraries like PIL), i have lost .py file association(when i double click my python scripts, windows asks me to choose a program to open it with instead of making python interpret it). How can i fix the issue?

This is not a programming question. Fixing this is done the same way you'd fix it any other time you had it. – kindall Sep 23 '12 at 17:45
    
"you'd fix it any other time you had it"?? – user1470033 Sep 23 '12 at 18:06

double-click again, lead Windows to pythonw.exe, and check the option that tells Windows to use it for all future .py files as well. – alexis Sep 23 '12 at 18:39

considering you've already set the path in environment variables:

open command prompt:

cd to the directory which contains lost.py and then type:

python lost.py and hit enter.

or using IDLE:

start IDLE --> press CTRL+O --> open your file --> press F5

why the downvote? – Ashwini Chaudhary Sep 23 '12 at 18:42
    
You got downvoted because you did not answer the question of "how do I fix my file associations" but instead answered "how do I run my python file". – Guvante Feb 16 at 18:53
