## Tip İçeren Yol Parametreleri

Standart Python tip belirteçlerini kullanarak yol parametresinin tipini fonksiyonun içerisinde tanımlayabilirsiniz.

```Python hl_lines="7"
{!../../../docs_src/path_params/tutorial002.py!}
```

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

!!! tip
    Make sure to use `yield` one single time.

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="6  47  54-55  58-59  68-74"
    {!> ../../../docs_src/security/tutorial004_py310.py!}

## Araştırma

Önceki alternatifleri kullanarak hepsinden bir şeyler öğrenip, fikirler alıp, bunları kendim ve çalıştığım geliştirici ekipler için en iyi şekilde birleştirebilme şansım oldu.

Mesela, ideal olarak standart Python tip belirteçlerine dayanması gerektiği açıktı.

    ```Python hl_lines="6  12-13"
    {!> ../../../docs_src/settings/app02_an/main.py!}
    ```

=== "Python 3.8+ 非注解版本"

    !!! tip
        如果可能，请尽量使用 `Annotated` 版本。

    ```Python hl_lines="5  11-12"
    {!> ../../../docs_src/settings/app02/main.py!}
    ```

!!! tip
    我们稍后会讨论 `@lru_cache`。

    目前，您可以将 `get_settings()` 视为普通函数。

然后，我们可以将其作为依赖项从“路径操作函数”中引入，并在需要时使用它。
