Also, it should have read from menagerie.cat import models as cat_models from menagerie.dog import models as dog_models from menagerie.mouse import

Also, it should have read from menagerie.cat import models as cat_models from menagerie.dog import models as dog_models from menagerie.mouse import models as mouse_models Because otherwise it doesn't match the code in the first example for #3, and also because if your packages are ordered that way, then why not just from menagerie.models import cat, dog, mouse and forget about changing the local module name.
