How to import from another folder (python)

Question

I have a folder structure like:

A/
+-- main.py
+-- bin/
+------ functions.py

I run the code with A as the current working directory.

Within the code of main.py, how do I import the functions.py file?

Answer 1

You need to create an empty file bin/__init__.py. This will tell python that bin is a "package" and should look for modules there.

from bin import functions

If you want to do something like from bin.functions import * you can add which functions you want to load defining them in __init__.py (more here)

# __init__.py
__all__ = ["fun1", "fun2"]
# doing import * will load those 2
