Cython 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. Cython gives you the combined power of Python and C …

Pure Python syntax which allows static Cython type declarations in pure Python code, following PEP-484 type hints and PEP 526 variable annotations. If you use the pure Python syntax we strongly recommend you use a recent Cython 3 release, since significant improvements have been made here compared to the 0.29.x releases.

Cython (/ ˈ s aɪ θ ɒ n /) is a superset of the programming language Python, which allows developers to write Python code (with optional, C-inspired syntax extensions) that yields performance comparable to that of C.

Cython is a Python compiler that makes writing C extensions for Python as easy as Python itself. Cython is based on Pyrex, but supports more cutting edge functionality and optimizations. Cython translates Python code to C/C++ code, but additionally supports calling C functions and declaring C types on variables and class attributes.

Feb 12, 2024 · In a gist, Cython automatically converts your Python code into C, which is fast and efficient. Here’s how we use it, say, in a Jupyter Notebook: Define every variable using the “cdef” keyword and specify its data type. A sample conversion of a …
