Python3: Import class problems

Suppose we have a tree like this:

└── my_project
    ├── A.py
    ├── __init__.py
    ├── my_apps
        ├── app_framework.py
        ├── app1.py
        ├── app2.py
        ├── __init__.py

Inside the folder my_apps, there is a general class defined in app_framework.py. The rest of the files all defines their own child class based on it.

The files would look like:

app_framework.py:

Class App():
    ...

app1.py:

from app_framework import App
Class MyApp1(APP):
    ...
    ...

app2.py:

from app_framework import App
Class MyApp2(APP):
    ...
    ...

So, in my project folder, I want to use

from my_apps import MyApp1, MyApp2

But I got two errors:

  1. First is ModuleNotFoundError: No module named app_framework. I partially fix it by changing from app_framework import App to from .app_framework import App

  2. ImportError: cannot import name 'MyApp1' from 'my_apps'

I can use from my_apps.app1 import MyApp1, MyApp2, but I would prefer from my_apps import MyApp1, MyApp2, which looks more concise. How to do it?

Create an __init__.py file in my_apps and import the required classes into that file:

# my_project/my_apps/__init__.py
from .app1 import MyApp1
from .app2 import MyApp2

Then in your A.py you can do:

from .my_apps import MyApp1, MyApp2
