There is no reason I can see for apack and bpack to be subpackages. Why not just rename atest.py as apack.py at the same level as the Test package's __init__.py, and in the same way make btest.py bpack.py. Then the __init__.py can do: from apack import printA from bpack import printB and your main program can do import Test Test.printA(...) regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden Sorry, the dog ate my .sigline so I couldn't cat it -- http://mail.python.org/mailman/listinfo/python-list
