# Generates and installs simple Cython modules with specified settings. If you are overwhelmed by the compiler directives and the creation of the setup.py file, this is right for you.
## Tested against Windows 10 / Python 3.11 / Anaconda
### pip install cythonautoinstall
This function takes Cython code along with various setup parameters and generates a
Cython module, compiles it, and installs it as a Python package. It handles the
generation of the Cython code, the creation of a setup script, compilation, and
installation. Made for people who write simple scripts and are overwhelmed
by the compiler directives and the creation of the setup.py file
