How To Use Logging In Multiple Modules?

Better Stack Team

Updated on May 4, 2022

It's recommended to have a logger defined in each module like this:

import logging
logger = logging.getLogger(__name__)

Copied!

Then in your main program, do the following:

import logging.config
logging.config.fileConfig('/path/to/logging.conf')

Copied!

If you want to use one logger, you can create a variable for the logging module:

import logging

logger = logging
logger.basicConfig()

Copied!

Then in other files, you will import the logger and use it from now on:

from base_logger import logger

Copied!

Every logger is a child of the parent's package logger. Meaning that all you need to do is configure the root logger.
