python logging set level in basicConfig

Question

python logging set level in basicConfig:

import logging

def show(level):
    logging.basicConfig(level=level)
    logging.info('info')
    logging.debug('debug')
    logging.warn('warn')
    logging.error('error')
    logging.fatal('fatal')
    logging.warning('warning')
    logging.critical('critical')
    logging.exception('exception')

show(logging.WARNING)
show(logging.DEBUG)

The two results are the same, how to get what I expects?

Answer 1

According to logging.basicConfig documentation, the second call to logging.basicConfig does not take effect.

This function does nothing if the root logger already has handlers configured for it.

def show(level):
    logger = logging.getLogger()
    logger.setLevel(level)
    logging.info('info')
    ....
