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?
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
You can find more info here.
from bin.functions import function1, function2To be able to do this, make surebin/has an__init__.py__init__.py
