Basic Tutorial — Cython 3.3.0a0 documentation
This syntax is mostly used in older code bases and in Cython modules that need to make use of advanced C or C++ features when interacting with C/C++ libraries. The additions to the syntax require a different file format, thus the .pyx extension: Python code ‘extended’. For this tutorial, assuming you have a Python programming background, it’s probably best to stick to the Python syntax examples and glimpse at the Cython specific syntax for comparison.

r/Python on Reddit: Writing entire programs in Cython
November 23, 2021 -

Hello everyone. I recently figured out how to use cython to speed up python programs, but there's one idea I have which is using cython to completely write python programs.

Cython is around 6.5 times faster than python (according to google) and nearly every function and module in python can be run in cython (if I'm correct), so I see why not to write my python scripts in cython completely and call them in regular python.

Is this a good idea? Would it be better to stick to regular python and only use cython when necessary? Or should I just use cython for every script I want to write?

Thanks in advance.

How do you run Cython in Windows?
Post by Canon If anyone is curious or ran into problems later on, here's 2 points that Unable to find vcvarsall.bat then you need to set minigw as the compiler, the following code should python setup.py build_ext --inplace --compiler=mingw32 2) The Cython tutorial I referenced earlier said you should see a .dll file after the Cython program compiles in Windows.
