### `examples`를 포함한 `Body`

여기, `Body()`에 예상되는 예제 데이터 하나를 포함한 `examples`를 넘겼습니다:

//// tab | Python 3.10+

```Python hl_lines="22-29"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="22-29"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

//// tab | Python 3.10+ без Annotated

/// tip | "Подсказка"

Предпочтительнее использовать версию с аннотацией, если это возможно.

///

```Python hl_lines="7  15"
{!> ../../docs_src/request_files/tutorial001_02_py310.py!}
```

////

//// tab | Python 3.6+ без Annotated

/// tip | "Подсказка"

Предпочтительнее использовать версию с аннотацией, если это возможно.

///

Здесь мы передаём аргумент `example`, как пример данных ожидаемых в параметре `Body()`:

//// tab | Python 3.10+

```Python hl_lines="22-27"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="22-27"
{!> ../../docs_src/schema_extra_example/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

## First dependency "dependable"

You could create a first dependency ("dependable") like:

//// tab | Python 3.10+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="8-9"
{!> ../../docs_src/dependencies/tutorial005_an_py39.py!}
```

////

//// tab | Python 3.8+

from ...utils import needs_py39


@needs_py39
def test_override_in_items_run():
    from docs_src.dependency_testing.tutorial001_an_py39 import test_override_in_items

    test_override_in_items()


@needs_py39
def test_override_in_items_with_q_run():
    from docs_src.dependency_testing.tutorial001_an_py39 import (
        test_override_in_items_with_q,
    )

    test_override_in_items_with_q()

First, import `OAuth2PasswordRequestForm`, and use it as a dependency with `Depends` in the *path operation* for `/token`:

//// tab | Python 3.10+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

Importieren Sie zunächst `OAuth2PasswordRequestForm` und verwenden Sie es als Abhängigkeit mit `Depends` in der *Pfadoperation* für `/token`:

//// tab | Python 3.10+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="4  78"
{!> ../../docs_src/security/tutorial003_an_py39.py!}
```

////

//// tab | Python 3.8+

So wie wir Pydantic zum Deklarieren von Bodys verwenden, können wir es auch überall sonst verwenden:

//// tab | Python 3.10+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py39.py!}
```

////

//// tab | Python 3.8+

First, let's create a Pydantic user model.

The same way we use Pydantic to declare bodies, we can use it anywhere else:

//// tab | Python 3.10+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="5  12-16"
{!> ../../docs_src/security/tutorial002_an_py39.py!}
```

////

//// tab | Python 3.8+

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:125,129:135,140,156] *}

Now let's review those changes step by step.
