Suppose I have a library written in Python that I'd like to call from a C software. Is there any way I can compile this Python code to a .so file?
This should help.
Also you can do both ways i.e. extend python by writing library in C and call it from Python code OR code functions in C that could be called from Python.
The standard term used (conceptually and help googling is "Python bindings"

NumPy is more the 35% written in other languages how do they work internally?
Python being an interpreted language, code written in it tends to be slow, because the interpreter needs to go through each line of the code being executed
because the performance is everything, modules are written in a lower level language like C which is then compiled to a shared object file. These files can be loaded by the Python interpreter and used like a normal python module. Because these modules are already compiled to machine code, they can be directly executed without going through the interpreter, and thus they are much faster than the equivalent code written in Python.
you can find a lot of modules written in c or c++ with extension .so
If you are using Python nowadays the most used implementation of Python is CPython wich is written in C, that mean that the interpreter of your python code is written in C
see here the repository of Python on Github,

I want to write golang bindings for an existing (third party) Python module.
The purpose is that I want to use the API that the Python module provides in Golang.
I already found golang bindings for Python's C API (go-python3 for py3 and go-python for py2), but I still haven't figured out how to translate a relatively complex Python module into Golang (i.e. how to deal with type safety in go for unsafe inputs and returns in python, etc).
What would be a good approach? Are there any pre-existing tools in that space? Are there any good examples for Golang bindings for Python code? (I couldn't find many tbh).
I want to use the API that the Python module provides in Golang.
Calling Python from Go is detailed recently in "Python and Go : Part I - gRPC" by Miki Tebeka.
You can see an example in ardanlabs/python-go/grpc
But, as shown in their next two articles, you can also:
compiled Go code to a shared library and used it from the Python interactive shell.
use a Python module that hides the low level details of working with a shared library and then package this code as a Python package.
Full example: ardanlabs/python-go/pyext.
I want to make a small application with graphical interface with Python but I want to do the calculations in another language such as C++ or Golang, is it possible ?
Build a .dll or .so file from your C++ source, then use Python's ctypes to import the functions from it. Alternatively, use the Python C API to create an extension module. The difference is that in the first approach, the interop code will be in Python, and in the second, it will be in your native code.
I'm working in an embedded Linux environment and I have some Python code which I would like to use. My Python code is just doing some math, not using any library other than Numpy and the common ones.
Is there any way to build up a library that I can call from C or C++ code?
Embedding the CPython interpreter into a C or C++ program is actually pretty straightforward.
The official documentation has some complete examples.
Also, check out SWIG and Boost.Python.
