Well, you can always do:: import(name) That's not much more verbose. Of course, to make it work with packages, you have to write something like:: mod = import(name) for submodname in name.split('.')[1:]: mod = getattr(mod, submodname) I guess that's not so simple after all.

Maybe this indicates a problem with import. Twisted has something called namedAny, and I always use that, because it just works, unlike import, which seems to take too many arguments and has weird behavior for dotted names.

me = namedAny(name)

The inverse is also available (qual(me) == name), and is another function I've always thought it strange was missing from the stdlib.
