pybox2d 2D Game Physics for Python https://github.com/pybox2d/pybox2d

pybox2d is a 2D physics library for your games and simulation. It's based on the Box2D library, written in C++. It supports several shape types (circle, polygon, thin line segments), and quite a few joint types (revolute, prismatic, wheel, etc.).

For building instructions, see INSTALL or the wiki on the homepage. Once installed, check out the testbed demos to see what pybox2d can do (located in examples/ ). Then read the manual located on the pybox2d wiki, here:

On the wiki, you will also find more useful things of varying quality. Here's the epydoc documentation:

It's by no means perfect, but it can come in handy.
