从 jupyter notebooks 调用外部 py 模块

Question

I have a project structure like this

I have some functions in utils.py which I want to use in aNotebook , so ran the pip install --editable command on my project and put the following in the first cell of the notebook

    %load_ext autoreload
    %autoreload 2

This I believe should allow me to do

    import src.constants
    from src.utils import write_data

    write_data(....)

But I'm having an issue where the constants defined in constants.py don't seem to stick. In other words, the functions in utils.py that are depending on the constants are not being defined at runtime.

What's more, in order to ensure that the constants are available to the function in utils.py without requiring the user to know they are required, utils.py imports the constants.py

My question , is there a primer on how to use Jupyter notebooks with plain old python modules such that both can reside in the same project? This seems like a lot of work for something that should be easy.

EDIT: Adding MVC and error

*** contents of src\\utils.py

def test1():
    return 'got to the test program'

Answer 1

I figured it out.

import os
import sys
# This adds the project root to the searchpath
sys.path.append(os.path.pardir)

# Then I can use 
from src.utils import test1
