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. Also Python and Lisp code can be mixed.
For rough documentation, please see the Introduction and Manual on common-lisp.net.
To install using QuickLisp: (ql:quickload "clpython") (require ASDF 3.3 or higher).
CLPython is developed by Willem Broekema and is released as open source under the LLGPL. The project was started in 2006, and is since 2013 not under active development anymore.
