Python Logging across multiple classes and files; how to configure so as to be easily disabled?

Question

Currently, I have osmething like this in all of my classes:

# Import logging to log information
import logging

# Set up the logger
LOG_FILENAME = 'log.txt'
logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG)

This works well, and I get the output I want, but I would really like to have all this sort of information in one place, and be able to just do something like import myLogger and then start logging, and then hopefully be able to just go into that file and turn off logging when I need an extra performance boost.

Thanks in advance

Answer 1

To disable all logging from the root logger (which is all you're setting up with basicConfig),

logging.getLogger().setLevel(logging.CRITICAL)

If you want, you can encapsulate that into a function of your myLogger module, but that hardly seems worth it.

Answer 2

To simply the setting up of logging, check out logging.config.

To disable logging, you could use the command

logging.disable(logging.CRITICAL)
