WebNov 29, 2024 · Cython can be considered both a module and a programming language that (sort of) extends Python by enabling the use of static typing borrowed from C/C++. Basically, all Python code is valid Cython, but not the other way around. Keep in mind, you can convert Python to Cython and vice versa. WebCython is an optimising static compiler for both the Python programming language and the extended Cython programming language (based on Pyrex). It makes writing C extensions for Python as easy as Python itself. If your code currently performs a lot of loops in Python, it might benefit from compilation with Cython.
