#pyscheme
Using pyscheme is fairly simple. It presently can access the Python C API and also allows some higher-level functionality, but is still very primitive. Here's an example of how to use it though:
> (require pyscheme/py)
> (init "libpython2.6")
> (pyimport os)
> os
"<module 'os' from '/home/jason/.virtualenvs/main/lib/python2.6/os.pyc'>"
