Questions tagged [pypy]

PyPy is an implementation of the Python language. Do not confuse with PyPI, the package index. General Python questions should just be tagged with python.

PyPy is a fast, very compliant, self-hosting implementation of the Python language. PyPy started out being a Python interpreter written in the Python language itself. It is built using the language.

PyPy has several advantages and distinctive features, including:

  • Speed: thanks to its Just-in-Time (JIT) compiler, Python programs often run faster on PyPy.

  • Sandboxing: PyPy provides the ability to run untrusted code in a fully secure way.

  • Stackless: PyPy can be configured to run in stackless mode, providing micro-threads for massive concurrency.

Programmers interested in following PyPy's progress should check the Dev Site and the PyPy Status Blog. For background, see PyPy - Goals and Architecture Overview.

Releases and builds

At this time there are three PyPy release series with binaries for x86, ARM, and PPC, on Linux, Mac OS/X and Windows:

  • PyPy2.7 v5.6.0 (the Python2.7 compatible release)
  • PyPy3.3 v5.5.0 (the Python3.3 compatible release)
  • PyPy-STM v2.5.1 (Linux x86-64 only)

More informations about builds and versions on download page. There are also nightly builds available.
