Cython: C-Extensions for Python
About Cython
Cython is a language that makes writing C extensions for the
Python language as easy as Python itself.
Cython is based on the well-known 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.
The generated C code compiles with Python 2.4 and later (including Python 3).This makes Cython the ideal language for wrapping external C libraries,
and for fast C modules that speed up the execution of Python code.Documentation
