[docs] Logging Cookbook: logging.Logger.setLevel faulty documentation

When I run the first code snippet in the Logging Cookbook: https://docs.python.org/3.7/howto/logging-cookbook.html I don't get any output. This is contrary to what it states "The output looks like this:". Since there is a lot of confusion around logging.Logger.setLevel (https://stackoverflow.com/questions/43109355/logging-setlevel-is-being-ignor...) I hope this can be resolved! Is the logging module itself perhaps malfunctioning? Thanks!
