Pure Python syntax which allows static Cython type declarations in pure Python code, following PEP-484 type hints and PEP 526 variable annotations. To make use of C data types in Python syntax, you need to import the special cython module …

Feb 11, 2025 · Cython is a source code translator based on Pyrex, but supports more cutting edge functionality and optimizations.

May 15, 2017 · Just directly install from pypi: https://pypi.org/project/Cython/ Use Pip3 command: I've undone an edit that changed pip3 -> pip since it seems to change the point of this answer.

Feb 28, 2022 · To get started, we’ll need to do three things: Create a copy of your python code with a .pyx extension. For this example, lets say our source file is solution.py, we’ll create solution.pyx. If you want to benchmark, rename the pyx file to something distinct like solution_cy.pyx, so you can import it specifically. Step 3 requires some detail.

Cython provides support for IPython to compile and run Cython programs. The pyximport module allows importing Cython programs directly.
