Hybrid C module + Python module (namespaces)

[purewack]

I there a way to write part of a custom module in C and then append Python defined functions to it during the build process using something in the form of frozen bytecode?

Example:

Suppose you have two files:

• modtest.c: defines a function called helloFromC()
• modtest.py: defines a function called helloFromPython()

The result I'm trying to achieve is something like:

>>> import modtest
>>> modtest.helloFromC()
>>> modtest.helloFromPython()

Essentially allowing to bundle modules under one 'namespace'

Can't you just create module _modtest with the c code in it, and then have modtest.py be

from _modtest import helloFromC

def helloFromPython():
   print("Hello")

This is how many of the main python library modules are handled, with low-level modules prefixed with '_'.

That's a good idea! I didn't think of obscuring the module and having a wrapper module. Great suggestion, thank you!

I did some testing, and this seems to be the most convenient solution. Thanks

Having two files is exactly that gets merged is exactly how the dynamic native modules build setup work. See for example, https://github.com/emlearn/emlearn-micropython/tree/master/src/emlearn_fft

Wow this seems even easier than the other way. 🤩
