Ever want to just turn off that logger for a while in Python? Maybe while running tests or debugging? Even the CRITICAL messages?

Notice that the logging level contants (logging.DEBUG etc) actually represent numeric values:

Level       Numeric value
ERROR       40
WARNING     30
INFO        20
DEBUG       10
NOTSET      0

On a whim I tried:


And bam, no logging, even the CRITICAL messages. Yes, most of you python nerds knew this, but I didn’t, so I learned something at least!
