> Please don't use __all__. At the moment, __all__ is the only way> to easily tell whether a particular module object really represents> a package, and the only way to get the list of submodule names.>> If __all__ is overloaded to also represent exportable symbols in> modules, these two pieces of information will be impossible (or> require much ugly hackery) to obtain.Marc-Andre already explained that __all__ is not to be trusted.If you want a reasonably good test for package-ness, use the presenceof __path__.For a really good test, check whether __file__ ends in __init__.py[c].--Guido van Rossum (home page:http://www.python.org/~guido/)
