Overview
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 language by Greg Ewing, but supports more cutting edge functionality and optimizations [1]. 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.
Future Plans
Cython is not finished. Substantial tasks remaining. See Limitations for a current list.
