Troubleshoot with `logging` instead of `print()`

Adding temporary print statements to troubleshoot Python code is quick and dirty. And messy. 

Incorporating logging into your code habit is a great alternative to relying on ad-hoc print statements that just need to get deleted later. 

The Basics

import logging

logging.basicConfig(format='%(message)s', level=logging.DEBUG)
logger = logging.getLogger()

Toggle DEBUG mode off/on

logger.disabled = True

Try it yourself

my_var = 'ABC'

logging.debug(f'my_var = {my_var}')
