Why do I get relative import error in python?

Question

I'm having this issue in python with relative imports, when I want to import a file from another folder I get an error.

File structure:

python/
  helpers/
    index.py
  posts/
    post.py

Then, I do in the posts/post.py file:

from ..helpers.index import conn

But when I run the python file, I get this error:

ImportError: attempted relative import with no known parent package

I don't really understand what I'm doing wrong. Especially that vscode understands that I'm trying to import this file

Thanks in advance
