Welcome to PyPy¶
The PyPy project aims to produce a flexible and fast Python implementation. This page documents the development of the PyPy project itself. If you don’t know what PyPy is, consult the PyPy website. If you just want to use PyPy, consult the download page and the getting started with pypy documents. If you want to help develop PyPy – keep reading!
PyPy is written in a language called RPython, which is suitable for writing dynamic language interpreters (and not much else). RPython is a subset of Python and is itself written in Python. If you’d like to learn more about RPython, Starting with RPython should provide a reasonable overview.
If you would like to contribute to PyPy, please read how to contribute first. PyPy’s development style is somewhat different to that of many other software projects and it often surprises newcomers. What is not necessary is an academic background from university in writing compilers – much of it does not apply to PyPy any way.
