And in case my comment wasn't obvious, Herbert is right about the error in the 
docs.

https://docs.python.org/3/extending/extending.html#the-module-s-method-table-and-initialization-function
 documents what Herbert discovered wrong in the porting docs.

The exact error was:

ImportError: dynamic module does not define init function (PyInit_myextension)

[issue26827] PyObject *PyInit_myextention -> PyMODINIT_FUNC PyInit_myextention

[Herbert]

New submission from Herbert:

I think 

PyObject *PyInit_myextention(void)

should be

PyMODINIT_FUNC PyInit_myextention(void)

on https://docs.python.org/3/howto/cporting.html#module-initialization-and-state

It didn't work for me until I replaced this with a message in the about 
'undefined PyInit_myextention'. However, when I used nm to inspect the .so 
object file, I fond the PyInit_myextention (but probably with the wrong return 
type). Moreover, whenever I would remove the same .so importing resulted in a 
different error complaining that the module does not exist (strongly suggesting 
that I did not mix up .so files).

Good luck!
