Yes, except that "from a import b" is not only used to import modules. It is pretty much defined to mean "b = getattr(a, 'b')". Consider this module: #foo.py # pull helper.helper from its implementation place from .helper import helper now, "from foo import helper" is expected to get the helper() function, not the helper module, but changing the semantics of the import statement would be "surprising".
