Python packages - import by class, not file

Question

Say I have the following file structure:

app/
  app.py
  controllers/
    __init__.py
    project.py
    plugin.py

If app/controllers/project.py defines a class Project, app.py would import it like this:

from app.controllers.project import Project

I'd like to just be able to do:

from app.controllers import Project

How would this be done?

You need to put

from project import Project

in controllers/__init__.py.

Note that when Absolute imports become the default (Python 2.7?), you will want to add a dot before the module name (to avoid collisions with a top-level model named project), i.e.,

from .project import Project

I wonder if it is possible to exclude at all the ability to call app.controllers.project.Project, in order to avoid having redundant paths to the same object (having both app.controllers.project.Project and app.controllers.Project at this point)
