    ```
    
    這表示 `item` 可以是 `int` 或 `str`。
    
    #### 可能為 `None` { #possibly-none }
    
    你可以宣告某個值可以是某個型別(例如 `str`),但它也可能是 `None`。

    ```
    
    ////
    
    使用 `str | None` 而不是單純的 `str`,可以讓編輯器幫你偵測錯誤,例如你以為某個值一定是 `str`,但它其實也可能是 `None`。
    
    ### 類別作為型別 { #classes-as-types }
    
    你也可以用類別來宣告變數的型別。

    `id`’nin SQL veritabanındaki **primary key** olduğunu söyler (SQL primary key’leri hakkında daha fazlasını SQLModel dokümantasyonunda öğrenebilirsiniz).
    
        **Not:** primary key alanı için `int | None` kullanıyoruz; böylece Python kodunda *`id` olmadan bir nesne oluşturabiliriz* (`id=None`) ve veritabanının *kaydederken bunu üreteceğini* varsayarız. SQLModel, veritabanının `id` sağlayacağını anlar ve *veritabanı şemasında sütunu null olamayan bir `INTEGER`* olarak tanımlar. Detaylar için [primary...

    函式參數的辨識方式如下:
    
    - 如果參數同時在**路徑**中宣告,則作為路徑參數。
    - 如果參數是**單一型別**(像是 `int`、`float`、`str`、`bool` 等),會被視為**查詢**參數。
    - 如果參數宣告為 **Pydantic 模型** 型別,會被視為請求**本文**。
    
    /// note
    
    FastAPI 會因為預設值 `= None` 而知道 `q` 的值不是必填。
    
    `str | None` 並非 FastAPI 用來判斷是否必填的依據;它會因為有預設值 `= None` 而知道不是必填。
    
    但加入這些型別註解能讓你的編輯器提供更好的支援與錯誤偵測。

    ## İsteğe bağlı parametreler { #optional-parameters }
    
    Aynı şekilde, varsayılan değerlerini `None` yaparak isteğe bağlı query parametreleri tanımlayabilirsiniz:
    
    {* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}
    
    Bu durumda, fonksiyon parametresi `q` isteğe bağlı olur ve varsayılan olarak `None` olur.
