Question

I’ve a main execution python file (F) where I would like to use some services (S)from other python class
the folder structure is :

root/a/my file to execute -- (F)
root/b/python class I would like to use -- (S)

how can I call to the requested python class (S) within my file (F)?

thanks.

This may be too obvious but other answers are missing the need to ensure that module b is in your sys.path. Thus assuming the folder structure in the question and assuming that directory b contains a file called __init__.py alongside the module s.py, then this incantation is needed:

# Add the b directory to your sys.path

import sys, os
parent_dir = os.getcwd() # find the path to module a
# Then go up one level to the common parent directory
path = os.path.dirname(parent_dir)
# Add the parent to sys.pah
sys.path.append(path)

# Now you can import anything from b.s
from b.s import anything
