### Bir *Yol Parametresi* Tanımlayalım

Sonrasında, yarattığımız enum sınıfını (`ModelName`) kullanarak tip belirteci aracılığıyla bir *yol parametresi* oluşturalım:

```Python hl_lines="16"
{!../../docs_src/path_params/tutorial005.py!}
```

### Dokümana Göz Atalım

*Yol parametresi* için mevcut değerler ön tanımlı olduğundan dolayı, interaktif döküman onları güzel bir şekilde gösterebilir:

### 声明*路径参数*

使用 Enum 类（`ModelName`）创建使用类型注解的*路径参数*：

```Python hl_lines="16"
{!../../docs_src/path_params/tutorial005.py!}
```

### 查看文档

 API 文档会显示预定义*路径参数*的可用值：

<img src="/img/tutorial/path-params/image03.png">

### 使用 Python _枚举类型_

*路径参数*的值是枚举的元素。

```Python hl_lines="6"
{!../../docs_src/response_status_code/tutorial001.py!}
```

`201`は「作成完了」のためのステータスコードです。

しかし、それぞれのコードの意味を暗記する必要はありません。

`fastapi.status`の便利な変数を利用することができます。

```Python hl_lines="1 6"
{!../../docs_src/response_status_code/tutorial002.py!}
```

それらは便利です。それらは同じ番号を保持しており、その方法ではエディタの自動補完を使用してそれらを見つけることができます。
