本文实例讲述了Python同时向控制台和文件输出日志logging的方法。分享给大家供大家参考。具体如下：

python提供了非常方便的日志模块，可实现同时向控制台和文件输出日志的功能。

#-*- coding:utf-8 -*-import logging# 配置日志信息logging.basicConfig(level=logging.DEBUG, format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s', datefmt='%m-%d %H:%M', filename='myapp.log', filemode='w')# 定义一个Handler打印INFO及以上级别的日志到sys.stderrconsole = logging.StreamHandler()console.setLevel(logging.INFO)# 设置日志打印格式formatter = logging.Formatter('%(name)-12s: %(levelname)-8s %(message)s')console.setFormatter(formatter)# 将定义好的console日志handler添加到root loggerlogging.getLogger('').addHandler(console)logging.info('Jackdaws love my big sphinx of quartz.')logger1 = logging.getLogger('myapp.area1')logger2 = logging.getLogger('myapp.area2')logger1.debug('Quick zephyrs blow, vexing daft Jim.')logger1.info('How quickly daft jumping zebras vex.')logger2.warning('Jail zesty vixen who grabbed pay from quack.')logger2.error('The five boxing wizards jump quickly.')

希望本文所述对大家的Python程序设计有所帮助。
