Not sure I understand what Marc-Andre is doing. (That's probably true in general <wink>.) A client of his code types "import foo.bar." foo is a module? a package? When the "bar" attribute is loaded (LOAD_ATTR) is turns into another module?

Take a look at e.g. mx.DateTime.__init__ and the included LazyModule module for more background. I don't really use that approach myself, but sometimes it can be handy to be able to reference modules in packages without requiring an import of them, e.g. import mx.DateTime date = mx.DateTime.Parser.DateTimeFromString('2002-02-01') -- Marc-Andre Lemburg CEO eGenix.com Software GmbH ______________________________________________________________________ Company & Consulting: http://www.egenix.com/ Python Software: http://www.egenix.com/files/python/
