I have been using [Python](http://en.wikipedia.org/wiki/Python_%28programming_language%29) on Windows for a while, so I'm into a lot of modules, including [Pygame](http://en.wikipedia.org/wiki/Pygame) and [LiveWires](http://tertial.livewires.org.uk/python/package?url=/python/package), but how do I install them into Ubuntu?

I have the py file for LiveWires, which has been specially edited (from a book I'm reading). I want to install it, but I'm not sure how to. I also want to install Pygame, but I can't.
