Welcome to PyPy!

PyPy is both an implementation of the Python programming language, and an extensive compiler framework for dynamic language implementations. You can build self-contained Python implementations which execute independently from CPython.

The home page is:

It will also point you to the rest of the documentation which is generated from files in the pypy/doc directory within the source repositories. Enjoy and send us feedback!

build with:

$ rpython/bin/rpython -Ojit pypy/goal/targetpypystandalone.py

This ends up with pypy-c binary in the main pypy directory. We suggest to use virtualenv with the resulting pypy-c as the interpreter; you can find more details about various installation schemes here:
