python logging.info does not print, logging.warn and logging.error does

Question

import logging

if __name__ == "__main__":
    logging.info('info')
    logging.warn('warning')
    logging.error('error')

Result:

warning
error

Why does logging.info not report anything?

Answer 1

Your log level is set so that 'info' won't print; by default it doesn't print anything less than WARNING. See Logger.setLevel.
