How to clear/reset all configured logging handlers in Python?

Question

My Situation
There may be one or more configured loggers, but I don't know what their names are.

Requirement
For testing purposes, I need to reconfigure logging handlers that were previously configured to log to stdout with a different format and logging level.

[caveat] I already know how to clear one handler.
[caveat] I would prefer stdlib over 3rd-party libs (pypi, github, et al).

print (logging.Logger.manager.loggerDict.keys())

found by digging the sources of logging package

LOL. I was totally going to answer my own question with the same thing. Thanks.

I think that dict does not include root logger handlers

Excellent, thank you. I still haven't found a simpler way to do it than this.
