Hmmm... it looks like you are correct and I made a mistake. This isn't something that the documentation is clear about, but here are a set of test files: $ cat A.py import __main__ import B print __main__, B, B.__main__ $ cat B.py import __main__ $ python A.py <module '__main__' from 'A.py'> <module 'B' from '/home/steve/python/ B.pyc'> <module '__main__' from 'A.py'> Here is the documentation: http://docs.python.org/library/__main__.html which is pretty sparse. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
