I am starting with my first Python project and choose to go with version 3.3 of the language. I'm doing this on a Kubuntu 13.04 x64 box. I appear to have both 2.7 and 3.3 installed (at /usr/bin/python and /usr/bin/python3.3).
Now I want to use some existing python packages (such as python nose) in my project. I tried installing nose using pip, but it looks like it is now installed for 2.7, and not 3.3.
Can I change the main python version of my system to 3.3 (which it breaking horribly - I know stuff in Ubuntu uses python, so am rather concerned this breaking my system). And if not, how can I best get the packages that I need to work on my 3.3 project?
