Where are the python modules stored?

Question

I have recently started learning Python and I have 2 questions relating to modules.

1. Is there a way to obtain a list of Python modules available (i.e. installed

Answer 1

1. You can iterate through directories listed in sys.path to find all modules (except builtin ones).
2. It'll probably be somewhere around /usr/lib/pythonX.X/site-packages (again, see sys.path). And consider using native Python package management (via pip or easy_install, plus yolk) instead, packages in Linux distros-maintained repositories tend to be outdated.
