WebThe fundamental nature of Cython can be summed up as follows: Cython is Python with C data types. Cython is Python: Almost any piece of Python code is also valid Cython code. (There are a few Limitations, but this approximation will serve for now.) The Cython compiler will convert it into C code which makes equivalent calls to the Python/C API.

WebApr 2, 2024 · The Cython language makes writing C extensions for the Python language as easy as Python itself. Cython is a source code translator based on Pyrex , but supports more cutting edge functionality and optimizations. WebCython is a hybrid Python/hinted language. In the most basic form it takes the Python code and makes a C file that wraps and calls the Python interpreter. In most cases this has little difference from just running the Python interpreter.
