duplicate output in simple python logging configuration

Question

I\'m setting up python logging as follows:

def setup_logging():
    loggers = (logging.getLogger(\"amcat\"), logging.getLogger(\"scrapers\"),logging.getLogge         


        

Answer 1

Basically, when one of your child logger displays a message, it goes backwards in the hierarchy, and the parents are also logging the same thing.

To cancel that behavior, you can add this:

logger.propagate = False

When it hits the child, it won't hit the parent afterwards.

Here is some documentation about this behavior.
