Python日志模块简单使用

def loginfo(info):

    # create logger

    logger = logging.getLogger('【cpu and mem】**********')

    # Set default log level

    logger.setLevel(logging.DEBUG)

    ch = logging.StreamHandler()

    ch.setLevel(logging.WARN)

    ch2 = logging.FileHandler(loginfofile)

    ch2.setLevel(logging.INFO)

    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s************* - %(message)s')  #设置日志格式

    ch.setFormatter(formatter)　　#添加到记录器

    ch2.setFormatter(formatter)

    logger.addHandler(ch)         #创建handler

    logger.addHandler(ch2)

    # 'application' code

    # logger.debug('debug message')

    logger.info('\n'+info)       #写入需要记录的日志

    logger.removeHandler(ch)          #写完log后一定要删除hender,不然会造成handler存在多个，写入重复的问题

    logger.removeHandler(ch2)
