### 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*

## Importar `Cookie`

Primero importa `Cookie`:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3]*}

## Declarar parámetros de `Cookie`

Luego declara los parámetros de cookie usando la misma estructura que con `Path` y `Query`.

El primer valor es el valor por defecto, puedes pasar todos los parámetros adicionales de validación o anotación:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[9]*}

代わりに、平文のパスワードを持つ入力モデルと、パスワードを持たない出力モデルを作成することができます:

```Python hl_lines="9 11 16"
{!../../docs_src/response_model/tutorial003.py!}
```

ここでは、*path operation関数*がパスワードを含む同じ入力ユーザーを返しているにもかかわらず:

```Python hl_lines="24"
{!../../docs_src/response_model/tutorial003.py!}
```

...`response_model`を`UserOut`と宣言したことで、パスワードが含まれていません:

```Python hl_lines="22"
{!../../docs_src/response_model/tutorial003.py!}
```

어트리뷰트를 서브타입으로 정의할 수 있습니다. 예를 들어 파이썬 `list`는:

```Python hl_lines="14"
{!../../docs_src/body_nested_models/tutorial001.py!}
```

이는 `tags`를 항목 리스트로 만듭니다. 각 항목의 타입을 선언하지 않더라도요.

## 타입 매개변수가 있는 리스트 필드

하지만 파이썬은 내부의 타입이나 "타입 매개변수"를 선언할 수 있는 특정 방법이 있습니다:

### typing의 `List` 임포트

먼저, 파이썬 표준 `typing` 모듈에서 `List`를 임포트합니다:

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

### 타입 매개변수로 `List` 선언

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[48:55] hl[51:52,54] *}

### Read One Hero

We can **read** a single `Hero`.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[58:63] hl[60] *}

### Delete a Hero

We can also **delete** a `Hero`.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[66:73] hl[71] *}

```Python hl_lines="15-23"
{!../../docs_src/schema_extra_example/tutorial001.py!}
```

Essas informações extras serão adicionadas como se encontram no **JSON Schema** de resposta desse modelo e serão usadas na documentação da API.
