pymunk is a easy-to-use pythonic 2d physics library that can be used whenever you need 2d rigid body physics from Python. Perfect when you need 2d physics in your game, demo or other application! It is built on top of the very nice 2d physics library Chipmunk.
To get started quickly take a look in the Readme, it contains a summary of the most important things and is quick to read. When done its a good idea to take a look at the included Examples, read the Tutorials and take a look in the API Reference.
“Make 2d physics easy to include in your game“
It is (or is striving to be):
pymunk has been tested and runs fine on both Python 2 and Python 3. It has been tested on recent versions of CPython (2 and 3) and Pypy. For an exact list of tested versions see the Readme.
Regardless of the method you use I will try to answer your questions as soon as I see them. (And if you ask on SO or the forum other people might help as well!)
If you like pymunk and find it useful and have a few minutes to spare I would love to hear from you. What would really be nice is a real postcard from the place where you are! :)
