Python extension package namespace

[Tu-Thach]

I have written a simple test extension module for Python and called it 
testxyz.  What I'd like to know is how can I make the module so that when 
I call it from Python I can use
from test.testxyz import *
instead of using
from testxyz import *
It's is pretty much like putting python code into packages.  I've tried 
putting it under a sub directory, but it doesn't work.  Anybody has any 
suggestions?

Thanks,
