Python 2.7 to Python 3

[anirudhbhardwaj19]

I have do just Installed Python 3.2 on my system but have to make it coexist with python 2.7 which is currently default with ubuntu 11

How can I remove 2.7 so and make python 3 the default .

Or when is the Debian default version change due !!

You can remove python2.7 with:



sudo apt-get remove python2.7 ; sudo apt-get autoremove


But if you just want to set a program to run with python3, then either launch it with:


python3 /path/to/file


or edit the first line (won't work on all scripts) to this:



#!/usr/bin/env python3


If something similar doesn't exist already in the script, add that line to the top (and don't replace anything).
