Add a logger

[eyad-hussein]

Replace all print statements with logs using python's builtin logging module.

import logging

make sure the output message has the correct logging level(look in the docs).

Also, make sure to name the logger object following pep 8 style.

Name the logger object as follows:

_LOG = logging.getLogger(__name__)

refer to the following docs:
https://docs.python.org/3/howto/logging.html#advanced-logging-tutorial

You can also look for more advanced tutorials if you are comfortable enough:
