    /// info | 資訊
    
    方括號裡的那些內部型別稱為「型別參數」。
    
    在這個例子中,`str` 是傳給 `list` 的型別參數。
    
    ///
    
    這表示:「變數 `items` 是一個 `list`,而這個清單中的每個元素都是 `str`」。
    
    這麼做之後,你的編輯器甚至在處理清單裡的項目時也能提供支援:
    
    <img src="/img/python-types/image05.png">
    
    沒有型別時,幾乎不可能做到這點。
    
    請注意,變數 `item` 是清單 `items` 中的一個元素。
    
    即便如此,編輯器仍然知道它是 `str`,並提供相應的支援。
    
    #### Tuple 與 Set { #tuple-and-set }
    
    你也可以用相同方式來宣告 `tuple` 與 `set`:

    使用瀏覽器開啟 [http://127.0.0.1:8000/items/5?q=somequery](http://127.0.0.1:8000/items/5?q=somequery)。
    
    你將會看到以下 JSON 回應:
    
    ```JSON
    {"item_id": 5, "q": "somequery"}
    ```
    
    你已經建立了一個具有以下功能的 API:
    
    * 透過路徑 `/` 和 `/items/{item_id}` 接受 HTTP 請求。
    * 以上兩個路徑都接受 `GET` 操作(也被稱為 HTTP _方法_)。
    * 路徑 `/items/{item_id}` 有一個 `int` 型別的路徑參數 `item_id`。
    * 路徑 `/items/{item_id}` 有一個可選的 `str` 查詢參數 `q`。
