Cython

Cython is a programming language and compiler that allows developers to write C extensions for Python. It enables the creation of Python modules with C-like performance by translating Python code into optimized C or C++ code, which can then be compiled into native machine code. This makes it particularly useful for speeding up computationally intensive Python applications.

Also known as: Cython language, Cython compiler, Cython extension, Cythonized Python, Pyrex (predecessor)

Why learn Cython?

Developers should learn Cython when they need to optimize performance-critical sections of Python code, such as in scientific computing, data analysis, or game development, where pure Python may be too slow. It is also valuable for integrating existing C/C++ libraries into Python projects, as it provides a seamless interface without requiring low-level C API knowledge.
