Welcome to Cython!

Cython is a language that makes writing C extensions for Python as easy as Python itself. Cython is based on Pyrex, but supports more cutting edge functionality and optimizations.

The Cython language is very close to the Python language, but Cython additionally supports calling C functions and declaring C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code.

This makes Cython the ideal language for wrapping external C libraries, and for fast C modules that speed up the execution of Python code.

Official website: https://cython.org/
Documentation: http://docs.cython.org/
Github repository: https://github.com/cython/cython
Wiki: https://github.com/cython/cython/wiki

You can support the Cython project via Github Sponsors or Tidelift.

Installation:

If you already have a C compiler, just do:

pip install Cython

otherwise, see the installation page.

License:

The original Pyrex program was licensed "free of restrictions" (see below). Cython itself is licensed under the permissive Apache License.

See LICENSE.txt.

Contributing:

Want to contribute to the Cython project? Here is some help to get you started.

We are currently building the next great Cython edition: Cython 3.0. You can help us make the life of Python 3.x users easier.

Get the full source history:

Note that Cython used to ship the full version control repository in its source distribution, but no longer does so due to space constraints. To get the full source history from a downloaded source archive, make sure you have git installed, then step into the base directory of the Cython source distribution and type:

make repo

The following is from Pyrex:

This is a development version of Pyrex, a language for writing Python extension modules.

For more info, see:

Doc/About.html for a description of the language
INSTALL.txt for installation instructions
USAGE.txt for usage instructions
Demos for usage examples

Comments, suggestions, bug reports, etc. are welcome!

The latest version of Pyrex can be found here.
