I'm trying to turn on debug logging in python 3.5.2:

import logging
log = logging.getLogger('test')
log.setLevel(logging.DEBUG)

log.warn('warn')
log.debug('debug')

log.root.setLevel(logging.DEBUG)
log.debug('debug again')

However, this only prints warn. What am I missing?

This should accomplish what you want

logging.basicConfig(level=logging.DEBUG)

…followed by

log = logging.getLogger('test')
log.debug('debug')

    Thanks for your answer. Using the root logger logging will also print logs from other python libraries. Is there a way to print debug-level logs using a logger obtained via logging.getLogger(), insted? Just like in the example provided by the OP.

  • @GuidoWalterPettinari this seemed to work for me (in other words, use log instead of logging): logging.basicConfig(level=logging.DEBUG) followed by log = logging.getLogger('test') followed by log.debug('debug')
