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)
