How to set Python's default version to 3.x on OS X?

Question

I\'m running Mountain Lion and the basic default Python version is 2.7. I downloaded Python 3.3 and want to set it as default.

Currently:

$ python
           


        

Answer 1

Go to 'Applications', enter 'Python' folder, there should be a bash script called 'Update Shell Profile.command' or similar. Run that script and it should do it.

Update: It looks like you should not update it: how to change default python version?
