create golang bindings for a python module

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).

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.
