Lisp to Python interface

I'm using LWW. I frequently interface C/C++ dll's using the FLI. Now I'm finding Python programs that I might like to include in my project - I don't know Python, but I'm wondering if there's some kind of a LWW to Python interface? Is it possible to interface Python directly? (Sorry if this is a stupid question.)

Maybe Willem Broekema's CLPython library does what you need?
See http://common-lisp.net/project/clpython/, which says:

   CLPython is an open-source implementation of Python written in
   Common Lisp.  With CLPython you can run Python programs in a Lisp
   environment. Libraries written in Lisp are available to Python code,
   and Python libraries can be accessed by Lisp code.

There are at least two options for accessing Python libraries from Lisp:

(1) with Python-on-Lisp you can execute any Python code from Lisp, and receive the results (using CFFI to interface with a normal Python installation)
(2) with CLPython you can import, compile and run pure Python libraries in Lisp (a reimplementation of Python in Lisp)

Some issues:

- Are those Python libraries written in pure Python, or are there also extension modules written in C? (Only Python-on-Lisp handles those C libraries.)

- Do you want to run functions in the Python library only for side effects? (Python-on-Lisp might be easier.)

- Are you interested in accessing Python functions and class instances from within Lisp and vice versa? (CLPython is going in this direction.)
