basicConfig中的python日志记录设置级别

Question

basicConfig 中的 python 日志设置级别:

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)

两个结果一样，如何得到我期望的？

根据 logging.basicConfig documentation ，第二次调用 logging.basicConfig 不生效。

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')
    ....
