解決python logging遇到的坑 日志重復打印問題

 self.logger = logging.getLogger(__name__)
 # 以下三行為清空上次文件
 # 這為清空當前文件的logging 因為logging會包含所有的文件的logging
 logging.Logger.manager.loggerDict.pop(__name__)
 # 將當前文件的handlers 清空 
 self.logger.handlers = []
 # 然後再次移除當前文件logging配置
 self.logger.removeHandler(self.logger.handlers)
 # 這裡進行判斷，如果logger.handlers列表為空，則添加，否則，直接去寫日志
 if not self.logger.handlers:
 # loggger 文件配置路徑
 self.handler = logging.FileHandler(os.getcwd() + '/logger/%s_log/%s_score.log' % (str(dt.date.today()), str(dt.date.today())))
 # logger 配置等級
 self.logger.setLevel(logging.DEBUG)
 # logger 輸出格式
 formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(name)s - %(message)s')
 # 添加輸出格式進入handler
 self.handler.setFormatter(formatter)
 # 添加文件設置金如handler
 self.logger.addHandler(self.handler)
 
 # 以下皆為重寫方法 並且每次記錄後清除logger
