Is there a way in python to get the list all defined loggers?

I mean, does something that can be used like logging.getAllLoggers() and which would return a list of Logger objects exist?



I searched the python.logging documentation but couldn't find such a method.



Thank you in advance.

          Loggers are held in a hierarchy by a logging.Manager instance. You could interrogate the Manager on the root logger for the loggers it knows about.



          import logging

          loggers = [logging.getLogger(name) for name in logging.root.manager.loggerDict]

          • In fact, getting the dict of Logger per name is better than simply a list of Logger alone, so logging.root.manager.loggerDict was exactly what I was searching for, thank you!
