那你可以宣告一個 `alias`，實際上就會用這個別名來讀取參數值：

{* ../../docs_src/query_params_str_validations/tutorial009_an_py310.py hl[9] *}

## 棄用參數 { #deprecating-parameters }

現在假設你不再喜歡這個參數了。

你必須暫時保留它，因為還有用戶端在用，但你希望文件能清楚標示它是<dfn title="過時，不建議使用">已棄用</dfn>。

接著把參數 `deprecated=True` 傳給 `Query`：

{* ../../docs_src/query_params_str_validations/tutorial010_an_py310.py hl[19] *}

文件會這樣顯示：

        setId_Terms(idList, opLambda);
