Python code and C code in the same module?

[Steven Bethard]

I'd like to merge a module written in C with a module written in Python
so that the user can access objects from either module by importing the
single, merged module.

Specifically, I'm looking at the collections module, which is written in
C, and my Bunch object, which is written in Python. I'd like the Bunch
object to appear in the collections module so that you can do:

from collections import Bunch

without, of course, removing the ability to do:

from collections import deque

There's no need for the code to reside in the same file or anything of
course -- I just want the different objects to appear in the same module.

Thanks,

Steve

the usual way to do this is to expose the C objects via the Python
module:

# foo.py
from _foo import flubb, glubb, dubb

# main.py
import foo

foo.flubb(flabb)

if you insist on doing it the other way around, you can emulate from-import
on the C level. see e.g. the "call" function in Modules/_sre.c for an example
(but instead of calling the "func", add it to the local module; see the "init_sre"
function in the same module for code that adds stuff to the module dict).
