Thanks so much, Phil! It works now. I never would have thought about
the reason why it didn't work.

Thanks a lot for looking into it!

It looks like the problem I'm having is caused by the namespace.
After removing the namespace, %Import works just fine. But We do
need to keep the namespace in our project. What do I need to do
to make it work?

It is working...

SIP implements a C++ namespace as a single Python class - in this case
A.SG.

It does not implement it as a separate class in each module. In other
words, in this case, it does not implement it as A.SG and B.SG.

When the B module is imported the contents of the SG namespace that it
implements are added to the SG class in the A module.

Your testB.py will work if you replace...

from B import *

...to...

import B
from A import SG

(Actually it doesn't matter what the order of these two lines are.)

I admit that all this isn't very obvious, and I might not do it this way
if I was doing it today.

Phil
