# You have no clue about C/C++, but want to boost Python using C/C++ code? Try this!

**cinpy** is made for people who never coded in C/C++, but want to use C/C++ functions/algorithms found somewhere on the internet (GitHub, Stack Overflow, ChatGPT …) in their Python code to speed things up.

### This module is not for massive frameworks, only for small scripts/code snippets. It is very simple and straightforward to use.

#### pip install cinpy

## Please install:

MSVC ..... C++ x64/x86 build tools from:
