How To Package A Python C Extension Such That It Is A Submodule Of A Normal Python Module?

I wrote a python library with two parts: A Python C extension A Python wrapper for the Python C extension I would like to be able to package it in such a way that the Python wrap

Solution 1:

As mentioned in the linked question, the solution is simply to change _foo to foo._foo:

from distutils.coreimport setup, Extensionmodule = Extension('foo._foo',
                   sources=['foo.c'])

setup(name='foo', packages=['foo'], ext_modules=[module])

My issue was that I was running my tests.py from the same directory as the foo module was located in.

I fixed this by bringing it into its own directory:

/foo
    /foo
        __init__.py
    foo.c
    setup.py
    /tests
         test.py
