I want to import something from a very high directory using sys

Question

Ok so the directories are on my D drive.

MainApp/main.py (The function which I want to import is in this file)

MainApp/subfolder/thirdfolder/fourthfolder/thisissohard.py (The file where I want to export the function to)

So I want to know how I can do this. I saw a tutorial on youtube but it only showed till the subdirectory but I want to go even deeper.

Any ideas?

Well I actually haven't tried anything yet because I am still confused. Here is the yt link: https://youtu.be/lR-OKnX7uOw — Aaseer, Oct 20 '21 at 12:44

For each folder, you need an __init__.py in that folder, for Python to recognize/treat it as a module, like the below imagined structure:

MainApp\
    .
    ├── main.py
    └── subfolder\
        ├── __init__.py
        └── thirdfolder\
            ├── __init__.py
            └── fourthfolder\
                ├── __init__.py
                └── thisissohard.py

Then, from main.py you can import like

import subfolder.thirdfolder.fourthfolder.thisissohard

or

from subfolder.thirdfolder.fourthfolder.thisissohard import foo, bar

Using sys.path.append() you can add you project root to the path:

import sys

sys.path.append('../../../../MainApp')

from MainApp.main import func
