Uses
Cython is particularly popular among scientific users of Python, where it has "the perfect audience" according to Python developer Guido van Rossum. Of particular note:
- The free software Sage computer algebra system depends on Cython, both for performance and to interface with other libraries.
- Significant parts of the scientific and numerical computing libraries SciPy and NumPy are written in Cython.
Cython's domain is not limited to just numerical computing. For example, the lxml XML toolkit is written mostly in Cython, and Cython is used to provide Pythonic bindings for many C and C++ libraries ranging from the graphics library OpenGL to the messaging library ZeroMQ.
