PyPy: Python in Python Implementation

Welcome to PyPy!

PyPy is an interpreter that implements the Python programming language, based on the RPython compiler framework for dynamic language implementations.

The home page for the interpreter is:

https://pypy.org/

If you want to help developing PyPy, this documentation might help you:

https://doc.pypy.org/

More documentation about the RPython framework can be found here:

https://rpython.readthedocs.io/

The source for the documentation is in the pypy/doc directory.

Using PyPy instead of CPython

Please read the information at https://pypy.org/ to find the correct way to download and use PyPy as an alternative to CPython.

Building

Building PyPy is not the recommended way to obtain the PyPy alternative python interpreter. It is time-consuming and requires significant computing resources. More information can be found here:
