Python-Mysql：多次嘗試連接 - 最佳實踐

我有以下的數據庫連接代碼，最初我沒有while循環多次嘗試，但後來我認爲它更好，我做了多次嘗試，才真正失敗它。我的問題是，完成這個的最好方法是什麼？我應該使用timmer嗎？並在再次嘗試之前做一些睡眠？Python-Mysql：多次嘗試連接 - 最佳實踐

while connect_attempts < 3: 
     try: 
      # dbname cann't have hyphen but host name can' 
      db_name = self.language.replace('-','_') + 'db' 
      print 'Connecting to DB ' + db_name 
      logging.info("Connecting to Toolserver MySql Db: " + db_name) 
      self.dbConnection = MySQLdb.connect(
       db=db_name, 
       host=self.language + "someserver_name.org", 
       read_default_file=os.path.expanduser("~/.my.cnf")) 
      logging.info("Connection Successful: " + str(self.dbConnection)) 
      self.dbCursor = self.dbConnection.cursor(cursors.DictCursor) 
     except MySQLdb.Error, e: 
      logging.error("Unable to establish connection MySQL ERROR - attempt-" + str(connect_attempt), e.value) 
      connect_attempts += 1
