[Python] Running Python functions from other files

I have created a number of .py files containing functions. The files would be organized in a Project_Repertory as follows:

Project_Repertory

• Load_Repertory
  • load_functions.py
  • main.py
• Automate_Repertory
  • main.py

In the Automate_Repertory I have a main.py file, which is to eventually be run using Apache Airflow (to which I am fully new), and I want to call the main() function of each of the other main.py files in the other folders.

However, if I write from Load_Repertory.main import main, it fails with a ModuleNotFound error. I tried working from the "Project_Repertory" instead, and then when I do from Load_Repertory.main import main it fails with the same error but pointing to a line in the code saying from load_functions import function1.

My Load_Repertory.main.py file looks like this:

import re
from load_functions import function1

def main()
print("This is main")
function1()

if __name__ == "__main__":
main()


I also tried importlib and runpy unsuccessfully. How do I import the main() from the Load_Repertory.main.py file and get it to run successfully if the terminal is open on the Automate_Repertory?

Details: Python 3.13.3 on Windows 11.
