```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。

#### 比较*枚举元素*

枚举类 `ModelName` 中的*枚举元素*支持比较操作：

```Python hl_lines="17"
{!../../../docs_src/path_params/tutorial005.py!}
```

#### 获取*枚举值*

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

### Documentation

Les valeurs disponibles pour le *paramètre de chemin* sont bien prédéfinies, la documentation les affiche correctement :

### Revisa la documentación

Debido a que los valores disponibles para el *parámetro de path* están predefinidos, la documentación interactiva los puede mostrar bien:

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

### Trabajando con los *enumerations* de Python

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

### Revise a documentação

Visto que os valores disponíveis para o parâmetro da rota estão predefinidos, a documentação interativa pode mostrar esses valores de uma forma bem legal:

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

### Trabalhando com os *enumeration* do Python

### *경로 매개변수* 선언

생성한 열거형 클래스(`ModelName`)를 사용하는 타입 어노테이션으로 *경로 매개변수*를 만듭니다:

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

### 문서 확인

*경로 매개변수*에 사용할 수 있는 값은 미리 정의되어 있으므로 대화형 문서에서 잘 표시됩니다:

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

### 파이썬 *열거형*으로 작업하기

*경로 매개변수*의 값은 *열거형 멤버*가 됩니다.

#### *열거형 멤버* 비교

열거형 `ModelName`의 *열거형 멤버*를 비교할 수 있습니다:

```Python hl_lines="10"
{!../../../docs_src/query_params/tutorial006.py!}
```

Ici, on a donc 3 paramètres de requête :

* `needy`, requis et de type `str`.
* `skip`, un `int` avec comme valeur par défaut `0`.
* `limit`, un `int` optionnel.
