Relative imports - ModuleNotFoundError No module named x

Question

I have these  two files:

1. test.py
2. config.py

These are the following functions stung to config.py:

config.py

debug = True

test.py

import config
print (config.debug)

But I am getting this error:

ModuleNotFoundError: No module named 'config'

The py3 convention is to use absolute imports:

from . import config

However, this leads to the following error:

ImportError: cannot import name 'config'

 Can someone help me solve this?
