Для этого используйте `typing.List` из стандартной библиотеки Python (или просто `list` в Python 3.9 и выше):

//// tab | Python 3.9+

```Python hl_lines="18"
{!> ../../docs_src/extra_models/tutorial004_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  20"
{!> ../../docs_src/extra_models/tutorial004.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="9"
{!> ../../docs_src/dependencies/tutorial011_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="8"
{!> ../../docs_src/dependencies/tutorial011_an.py!}
```

////

//// tab | Python 3.8+ nicht annotiert

/// tip | "Tipp"

你还可以通过将默认值设置为 `None` 来将请求体参数声明为可选参数：

//// tab | Python 3.10+

```Python hl_lines="18-20"
{!> ../../docs_src/body_multiple_params/tutorial001_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="18-20"
{!> ../../docs_src/body_multiple_params/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="19-21"

//// tab | Python 3.10+

```Python hl_lines="2"
{!> ../../docs_src/body/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="4"

## 여러분의 데이터 모델 만들기

`BaseModel`를 상속받은 클래스로 여러분의 데이터 모델을 선언합니다.

모든 어트리뷰트에 대해 표준 파이썬 타입을 사용합니다:

//// tab | Python 3.10+

```Python hl_lines="5-9"

Then create class attributes with fixed values, which will be the available valid values:

```Python hl_lines="1  6-9"
{!../../docs_src/path_params/tutorial005.py!}
```

## `Cookie` 임포트

먼저 `Cookie`를 임포트합니다:

//// tab | Python 3.10+

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001_an.py!}
```

Luego crea atributos de clase con valores fijos, que serán los valores disponibles válidos:

```Python hl_lines="1  6-9"
{!../../docs_src/path_params/tutorial005.py!}
```
