• 在logging的基礎上封裝一個簡易的日誌處理類，同時輸出到日誌檔案和列印到螢幕

#coding=utf-8
import logging
import logging.handlers

class Log:
    __file = 'log.log'#日誌檔名稱
    __handler = False
    __fmt = '%(asctime)s - %(filename)s:[line:%(lineno)s] - %(name)s - %(message)s'#輸出格式

    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)
        #列印
        self.__handler = logging.StreamHandler()
        self.__handler.setLevel(logging.INFO)

        #設定格式
        formatter = logging.Formatter(self.__fmt)
        self.__handler.setFormatter(formatter)
        return
 


    #獲取例項
    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")
