Where do packages install to?

Miscellaneous Forums/Linux Discussion/Where do packages install to?

I'm playing around with Ubuntu 6.10 and have installed a few packages from the manager.
I installed a Python editor + source code examples but I just don't know where the source code is.

What folder should I look in?

I tried serching for *.py and got a list of what seems to be functions which do nothing at all when I run them.

Is there a general way to find out where things went?
