Python: Calling a module in same directory

Question

I have trouble importing a module in same directory. Basically, here is my organization

alex (folder)
 |
 |- alex (folder)
 |   |- __init__.py
 |   |- commons.py
 |   |- KnowledgeBase.py
 |
 |- test.py

in my init.py file, I have the following lines to make import of commons & KnowledgeBase easier in test.py. It appears to work.

from .KnowledgeBase import KnowledgeBase
from .commons import *

In my KnowledgeBase.py file, I have a class called KnowledgeBase.

In commons.py, I have different objects:

• a namedtuple called CDE

• an object called TimePeriod

And then, in test.py, I can call my objects this way.

import alex as al
do stuff with al.KnowledgeBase
do stuff with al.CDE
do stuff with al.TimePeriod

What doesn't work now.

I am calling in KnowledgeBase.py the module commons.py.

import alex as al
stuff with al.CDE ...

I get the following error message.

AttributeError: module 'alex' has no attribute 'CDE'

If I do it the traditional way:

import commons as AC
stuff with AC.CDE ...

I get the following error message.

ModuleNotFoundError: No module named 'commons'

And if I remove everything in the init.py file, it works, but then, I cannot use "easy module call" in test.py.

If I keep an empty init.py file, in test.py, instead of simply writing

import alex

I have to declare all imports:

from alex import KnowledgeBase
from alex import commons

Please, what can I do to keep the import of the different python modules in alex "simple" and at the same time, being able to import module from alex folder into other modules in alex folder?

I thank you in advance for your help. Have a good afternoon, Bests,

I come back after having found the appropriate formatting. In KnowledgeBase.py, the correct way to import functions or objects from commons is by typing:

from . import commons as AC
