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

Mac users just need to run the following code on terminal

brew switch python 3.x.x

3.x.x should be the new python version.

This will update all the system links.
