How to add modules from external directories in Python

Question

I know this must be fairly easy but I cannot make it work for my case. I have the following structure:

project_root
    __init__.py
    backend
        __init__.py
        application
            __init__.py
            admin
                __init__.py
                models
    scheduling
        __init__.py
        my_script.py

I want to load some objects from __init.py__ file under application as well as some other objects from models.py file under application.admin .

How to do that without using sys.path or similar technique?

Answer 1

You can set the environment variable PYTHONPATH to the root directory of your project. Python will look for modules there.

Answer 2

It depends on your entry point.

If I am reading your question correctly, you would like to access objects in application/__init__.py from code within admin/models.py?

If your entry point is __init__.py in the project_root folder ie.

user@host:/$python project_root/__init__.py

Then from within your models.py code you can simply write:

from backend.application import myobject
