How do I configure __init__.py in this situation?

I have a python application with the following structure.

/app
  /models
    __init__.py
    profile.py
  /views
    __init__.py
    index.py
    login.py
  __init.py
main.py

Currently the three __init__.py files are empty.

In the files like index.py, I have several classes.

class IndexHandler(webapp2.RequestHandler):
    #blah blah

What do I write in the __init.py__ files such that I can call the classes in profile.py, index.py and so on without typing the full package path?

Namespaces in Python are explicit. In each __init__.py file, import whatever modules, functions, and classes you would like to be available within the namespace of that package.

For example, if you would like the app package to have an index member, in /app/__init__.py:

from views import index

Or if you would like the class itself to be part of the namespace:

from models.views import IndexHandler

This will allow you to do:

import app
handler1 = app.index.IndexHandler()  # example 1
handler1 = app.IndexHandler()  # example 2

You technically don't have to put anything in the __init__.py file. You should be able to import models from your main.py file, as long as it is in the app folder, and use the functions like:

import models    
models.profile.whatever

If you main.py is 'above' your /app folder, you will need an __init__.py file in your /app folder. then you can do:

import app
app.models.profile.whatever
