Circular import dependency in Python

Question

Let\'s say I have the following directory structure:

a\\
    __init__.py
    b\\
        __init__.py
        c\\
            __init__.py
            c_file.p         


        

Answer 1

I've wondered this a couple times (usually while dealing with models that need to know about each other). The simple solution is just to import the whole module, then reference the thing that you need.

So instead of doing

from models import Student

in one, and

from models import Classroom

in the other, just do

import models

in one of them, then call models.Classroom when you need it.
