Python Cannot Import from the src/ Directory

Question

I have a project with this structure:

root-project/
    src/
        utils/
            file_check.py
        main.py
        type_aliases.py
    ...

In the src/utils/file_check.py I import something from src/type_aliases.py but I always get a ModuleNotFound exception. These are what I have tried:

from src.type_aliases import ...

I also removed the src.:

from type_aliases import ...

These are the exceptions:

ModuleNotFoundError: No module named 'src'

The second one:

ModuleNotFoundError: No module named 'type_aliases'

I ran the files through the root-project/ directory, however, I also switched to the src/ directory but I still got the exception.

I also checked the sys.path variable and added src/ directory but I still get the error:

import sys

sys.path.append("/home/eastern-skill7173/dev/python/root-project/src/")

from src.type_aliases import ...

Still the error is visible

When you add the src directory to sys.path, this directory will be searched for modules during import. Hence, you can import modules directly by their name:

import sys

sys.path.append("/path/to/src")

import type_aliases
