create golang bindings for a python module

Question

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).

Answer 1

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.
