本文實例講述了Python同時向控制臺和文件輸出日志logging的方法。分享給大家供大家參考。具體如下：

python提供了非常方便的日志模塊，可實現(xiàn)同時向控制臺和文件輸出日志的功能。

#-*- 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')# 定義一個Handler打印INFO及以上級別的日志到sys.stderrconsole = logging.StreamHandler()console.setLevel(logging.INFO)# 設(shè)置日志打印格式formatter = logging.Formatter('%(name)-12s: %(levelname)-8s %(message)s')console.setFormatter(formatter)# 將定義好的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.')

希望本文所述對大家的Python程序設(shè)計有所幫助。
