Es sollte eine `list`e von `Depends()` sein:

//// tab | Python 3.9+

```Python hl_lines="19"
{!> ../../docs_src/dependencies/tutorial006_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="18"
{!> ../../docs_src/dependencies/tutorial006_an.py!}
```

////

//// tab | Python 3.8 nicht annotiert

/// tip | "Tipp"

///

//// tab | Python 3.10+

```Python hl_lines="1  14-15  18-20  33"
{!> ../../docs_src/extra_models/tutorial003_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="1  14-15  18-20  33"
{!> ../../docs_src/extra_models/tutorial003.py!}
```

////

## 模型列表

使用同样的方式也可以声明由对象列表构成的响应。

为此，请使用标准的 Python `typing.List`：

//// tab | Python 3.9+

//// tab | Python 3.10+

```Python hl_lines="16  21"
{!> ../../docs_src/response_model/tutorial001_01_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="18  23"
{!> ../../docs_src/response_model/tutorial001_01_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="18  23"
{!> ../../docs_src/response_model/tutorial001_01.py!}

//// tab | Python 3.10+ Pydantic v2

```Python hl_lines="13-24"
{!> ../../docs_src/schema_extra_example/tutorial001_py310.py!}
```

////

//// tab | Python 3.10+ Pydantic v1

```Python hl_lines="13-23"
{!> ../../docs_src/schema_extra_example/tutorial001_py310_pv1.py!}
```

////

//// tab | Python 3.8+ Pydantic v2

```Python hl_lines="15-26"

//// tab | Python 3.10+

```Python hl_lines="28-33"
{!> ../../docs_src/body_updates/tutorial001_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="30-35"
{!> ../../docs_src/body_updates/tutorial001_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="30-35"
{!> ../../docs_src/body_updates/tutorial001.py!}
```

```Python
q: Union[str, None] = None
```

Ou como em Python 3.10 e versões superiores:

```Python
q: str | None = None
```

Por exemplo:

//// tab | Python 3.10+

```Python hl_lines="26"
{!> ../../docs_src/body_multiple_params/tutorial004_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="27"

## 导入 Path

首先，从 `fastapi` 导入 `Path`：

//// tab | Python 3.10+

```Python hl_lines="1  3"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="1  3"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="3-4"

//// tab | python 3.9+

```python hl_lines="18-19  26-27"
{!> ../../docs_src/dependencies/tutorial008_an_py39.py!}
```

////

//// tab | python 3.8+

```python hl_lines="17-18  25-26"
{!> ../../docs_src/dependencies/tutorial008_an.py!}
```

////

//// tab | python 3.8+ non-annotated

/// tip | "Dica"

Utilize a versão com `Annotated` se possível.

///

//// tab | Python 3.10+

```Python hl_lines="8  49  56-57  60-61  70-76"
{!> ../../docs_src/security/tutorial004_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="8  49  56-57  60-61  70-76"
{!> ../../docs_src/security/tutorial004_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="8  50  57-58  61-62  71-77"

<div class="termy">

```console
$ python -m venv .venv
```

</div>
