Create a DLL to allow using Python code from C++

Question

I am looking for a way to convert Python code (using numpy, PyQt5, and other libraries) into a file .dll which can be used by other langage as C, LabVIEW or C++. This is to avoid to recode all my algorithms in C++ to create pure C++ dll. I also want to avoid seeing the source code and all the scripts being one script like an .exe

I've read a lot on the subject, but haven't found anything true. Sometimes a really complicated way was described or something that didn't work

1. The first thing I need to know is if it works at all?
2. Next I need a very simple tutorial. It would be best to convert a Python function into a DLL, which I can then call from C++.
