Avoid warning from module in different folder with Pylance in VSCode

Question

I have the following folder structure:

/mypythonproject
../modules
....mycustomfunctions.py
../script
....script.py

Inside the file script.py I declare the following:

import sys
sys.path.insert(1, '../modules')
from mycustomfunctions import function_a

script.py work just fine, but Visual Studio Code shows a warning on this:

from mycustomfunctions import function_a

Telling me that: Import "mycustomfunctions" could not be resolved

Is there something I can improve?

Answer 1

It seems that Pylance "prefers" the dot notation with __init__.py. In my example, one should create a blank __init__.py file inside the /modules folder:

/mypythonproject
../modules
....__init__.py
....mycustomfunctions.py
../script
....script.py

And then, in script.py, import the module as follows:

from mypythonproject.modules.mycustomfunctions import function_a

This is not showing any warning in the editor and works as expected.
