You are right, but we were talking about a slightly different scenario. To make things clear: 1) import MMA xx=MMA.grooves.somefunc() 2) import MMA.grooves xx=MMA.grooves.somefunc() If MMA is a module, containing a class named gooves, those two ways are valid. If MMA is a package, and grooves is a module contained in the package, only the second one is valid (assuming the package has an empty __init__.py, or does not import grooves itself) The OP was asking why the second form worked fine for him for a while, but stopped working after reordering some imports. And the answer (according to "Greg") is: some other module imported MMA.grooves, and that put grooves into MMA namespace, available for everyone else. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
