Python 封装使用日志处理类

• 在logging的基础上封装一个简易的日志处理类，同时输出到日志文件和打印到屏幕

#coding=utf-8import loggingimport logging.handlersclass Log:    __file = 'log.log'#日志文件名称    __handler = False    __fmt = '%(asctime)s - %(filename)s:[line:%(lineno)s] - %(name)s - %(message)s'#输出格式    def __init__(self):         logging.basicConfig(filename=self.__file, filemode='a+', format=self.__fmt)        # self.__handler = logging.handlers.RotatingFileHandler(self.__file, maxBytes=1024*1024, backupCount=5)        #打印        self.__handler = logging.StreamHandler()        self.__handler.setLevel(logging.INFO)        #设置格式        formatter = logging.Formatter(self.__fmt)        self.__handler.setFormatter(formatter)        return    #获取实例    def getInstance(self, strname):        logger = logging.getLogger(strname)        logger.addHandler(self.__handler)        logger.setLevel(logging.DEBUG)        return logger 

• 使用demo

if __name__=="__main__":    testlog = Log().getInstance("test")    testlog.info("info log")    testlog.debug("debug log")    testlog.warning("waring log")
