python_select

[Joshua Root]

If you want to run 'python', use python_select. This can be linked to 
any version of python. If you want to run 'python2' or 'python3', use 
the others. These can only be linked to python 2.x or 3.x respectively. 
A common use for this might be if you have scripts that only work with 
one or the other, in which case you can start them with something like 
'#!/usr/bin/env python2'.
