Facts

What it does
Cython is an optimising static compiler for Python and the extended Cython language, used to write C extensions for Python.cython.org · 30 Sept 2026
Generated code
Cython translates source code into C or C++ code that can be compiled as Python extension modules.docs.cython.org · 30 Sept 2026
Static typing
Optional static type declarations can help generate more efficient C code from Python-like code.docs.cython.org · 30 Sept 2026
C and C++
Cython lets Python code call C or C++ code and supports declaring C or C++ types.cython.org · 30 Sept 2026
Debugging
Cython supports combined source-level debugging across Python, Cython and C code.cython.org · 30 Sept 2026
Data and libraries
