[FIXED] How to import a Python module from a sibling folder?

Issue

I have gone through many Python relative import questions but I can't understand the issue/get it to work.

My directory structure is:

Driver.py

A/
      Account.py
      __init__.py

B/
      Test.py
      __init__.py

Driver.py

from B import Test

Account.py

class Account:
def __init__(self):
    self.money = 0

Test.py

from ..A import Account

When I try to run:

python Driver.py

I get the error

Traceback (most recent call last):

from B import Test

File "B/Test.py", line 1, in <module> from ..A import Account

ValueError: Attempted relative import beyond toplevel package

Solution

This is happening because A and B are independent, unrelated, packages as far as Python is concerned.

Create a __init__.py in the same directory as Driver.py and everything should work as expected.
