Logging setLevel is being ignored

Question

The below code is copied from the documentation. I am supposed to be able to see all the info logs. But I don\'t. I am only able to see the warn and above even though I\'ve

Answer 1

You have to set the basicConfig of the root logger to DEBUG, then you can set the level of your individual loggers to more restrictive levels.

This is not what I expected. Here is what I had to do:

#!/usr/bin/env python3

import logging
# by default this is WARNING.  Leaving it as WARNING here overrides 
# whatever setLevel-ing you do later so it seems they are ignored.
logging.basicConfig(level=logging.DEBUG)

l = logging.getLogger(__name__)
l.setLevel(level=logging.INFO)
# if I hadn't called basicConfig with DEBUG level earlier, 
# info messages would STILL not be shown despite calling 
# setLevel above.  However now debug messages will not be shown 
# for l because setLevel set it to INFO

l.warning('A warning message will be displayed')
l.info('A friendly info message will be displayed')
l.debug('A friendly debug message will not be displayed')
