Python3日誌模塊簡單實現

import logging
def log(logname='log',level='info',title='log',message='logout'):
    # 創建一個logger
    logger = logging.getLogger('[%s]'%(title))
    logger.setLevel(logging.DEBUG)
    # 創建一個handler，用於寫入日誌文件
    fh = logging.FileHandler('%s.log'%(logname))
    # 定義handler的輸出格式
    formatter = logging.Formatter('%(asctime)+s  %(name)+s  %(levelname)+s  %(message)+s')
    fh.setFormatter(formatter)
    # 給logger添加handler
    logger.addHandler(fh)
    # 寫入日誌
    if level=='debug':
        logger.debug('%s'%(message))
    elif level=='warning':
        logger.warning('%s' % (message))
    elif level=='error':
        logger.error('%s' % (message))
    else:
        logger.error('%s' % (message))


logname='20191219'
message='this is a test message!'
#log(logname='1219',level='info',title='log',message='logout')
log('%s'%(logname,),'debug','recv','%s'%(message,))
