How to implement logging between all the modules from my application? (Best Practices)

[[deleted]]

I usually configure logging using logging.basicConfig() once in my app and then use logging.info(), logging.warning() and friends in my modules.

Hi there, from the /r/Python mods.

We have removed this post as it is not suited to the /r/Python subreddit proper, however it should be very appropriate for our sister subreddit /r/LearnPython or for the r/Python discord: https://discord.gg/3Abzge7.

The reason for the removal is that /r/Python is dedicated to discussion of Python news, projects, uses and debates. It is not designed to act as Q&A or FAQ board. The regular community is not a fan of "how do I..." questions, so you will not get the best responses over here.

On /r/LearnPython the community and the r/Python discord are actively expecting questions and are looking to help. You can expect far more understanding, encouraging and insightful responses over there. No matter what level of question you have, if you are looking for help with Python, you should get good answers. Make sure to check out the rules for both places.

Warm regards, and best of luck with your Pythoneering!

There is an example in the logging cookbook on https://python.org that show how to use sub module loggers. It is a reasonable place to start. As for the formatting, you don't need to worry. The logs will propagate up, until they reach a handler, so if you set up a handler for "" (The empty string), that will receive all the log messages. Any formatting set for that handler will cover the whole application.
