I am logging messages from various modules and want to change the log level dynamically. The code snippet is

import logging
logging.basicConfig(filename='my_log.log', filemode='w', encoding='utf-8', level=logging.WARNING, force=True)

# Code here that works so only worry about WARNINGs
# ....

# Code here has an issue so increase log level to DEBUG

logging.setLevel(logging.DEBUG)

This gives the error AttributeError: module 'logging' has no attribute 'setLevel'. I tried using the logger generated by basicConfig, e.g.

L = logging.basicConfig(filename='my_log.log', filemode='w', encoding='utf-8', level=logging.INFO, force=True)
L.setLevel(logging.DEBUG)

but got the error AttributeError: 'NoneType' object has no attribute 'logging'. How can I do this?

  • Do you mean that you get AttributeError: 'NoneType' object has no attribute 'setLevel' in the last example? Commented Feb 13, 2024 at 10:35

  • Hi both - thanks for the link to the solution. I changed my code to logging.getLogger().setLevel(logging.DEBUG) and it works as expected Commented Feb 13, 2024 at 12:19
