It exists in python2.1 - I don't have an older python to check at the moment. > A word of warning (although I would guess you are already aware of > these issues, but for other readers): this method can't tell the > difference between a class defined in the module and a class imported > into it. > > Finally, despite the warning, I think you are ok to use dir() for that > purpose. It's not likely to change. Good advice... And as a double check >>> import sys >>> set(sys.__dict__.keys()) == set(dir(sys)) True >>> import os >>> set(os.__dict__.keys()) == set(dir(os)) True -- Nick Craig-Wood <n...@craig-wood.com> -- http://www.craig-wood.com/nick -- http://mail.python.org/mailman/listinfo/python-list
