I have python3.2 located in /usr/lib/python3.2. I am not sure if that means it's installed but I assume it is for now.

Some facts about my system:

$ which python

/usr/local/bin/python

When I type python in terminal I get the following

$ python

Python 2.7.2 (default, Dec 19 2011, 11:12:13) 

[GCC 4.4.3] on linux2

Type "help", "copyright", "credits" or "license" for more information.

Then to find the path I do

>>> sys.info

>>> sys.path

['', '/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg', '/usr/local/lib/python2.7/site-packages/pip-1.0.2-py2.7.egg', '/usr/local/lib/python2.7/site-packages/PIL-1.1.7-py2.7-linux-x86_64.egg', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']

So knowing all of this, how do I change my default system python from 2.7.2 to 3.2?
