question about import
I'm a little unclear about import / __import__ I'm exploring dynamically importing modules for a project, and ran into this behavior works as expected: app = __import__( myapp ) appModel = __import__( myapp.model ) but... appname= 'myapp' app = __import__( "%s" % appname ) appModel = __import__( "%s.model" % appname ) In the latter example, app and appModel will always seem to be imported as 'myapp' , and I've yet to find a way to address the .model namespace I know 'dynamically importing modules' is cursed upon -- and I'm likely rewriting hundreds of line of codes so I can work around this with a registration system -- however I'd like to understand why this occurs and know if what i'm trying is even possible. -- http://mail.python.org/mailman/listinfo/python-list

I didn't either. Until I asked some people how to do it, and was
admonished for even suggesting the concept.

interesting approach. unfortunately, it raises AttributeError: 'a'
object has no attribute 'b'
i think i'm going to table this approach. sigh.
