ModuleNotFoundError in absolute folder structure

This may be answered somewhere else but I cannot find a solution.

I have these two folder structures:

app/
  service/
    __init__.py
    caller.py
    ...
  utils/
    __init_.py
    config.py
    ...
  __init__.py
  ...

In caller.py I have:

from app.utils import config

When I run python caller.py (from cd to app/service) I get:

from app.utils import config
ModuleNotFoundError: No module named 'app'

However, if I move caller.py to the app folder and use the following import line:

from utils import config

It works. Why? I've also tried using .app.utils, ..utils, etc., but to no avail.

If you add the parent directory to the path, then when changing into directory "/app/service", Python will find the neighboring "utils" directory.

caller.py

import sys

sys.path.insert(1, '../')

from utils import config

print(f"Caller imported config value SETTING_X: {config.SETTING_X}")

config.py

SETTING_X = 42

Output

Caller imported config value SETTING_X: 42
