Python 3D libraries

I'd like to start making a little 3D mini-game in Python as a side project. What libraries would you suggest to do this? Should I just use pygame + pyopengl? Is there a decent 3D game engine in Python? Or do people just choose a foss sepples engine with Python bindings instead? I have quite a lot of OpenGL experience in C/C++ from my day job so I'm comfortable with it, but if there's a simple python library to load up 3D meshes and render them that would make things a lot easier. Not looking for a full-fledged 3D engine with scene management etc; just a simple API for loading and rendering.

Also, in before Lisp.
