=== "Python 3.10+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial004_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-50"

Sie können es so verwenden:

=== "Python 3.10+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-50"

You can use it like this:

=== "Python 3.10+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-50"

이를 다음과 같이 사용할 수 있습니다:

=== "Python 3.10+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="23-49"
    {!> ../../../docs_src/schema_extra_example/tutorial005_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="24-50"

      .isEqualTo(date("2021-06-09T10:18:14.000+0000"))
    assertThat(Date(parse(url, "a=b; Expires=Sun, 06 Nov 1994 08:49:37 GMT")!!.expiresAt))
      .isEqualTo(date("1994-11-06T08:49:37.000+0000"))
  }

  @Test fun awkwardDates() {
    assertThat(parse(url, "a=b; Expires=Thu, 01 Jan 70 00:00:00 GMT")!!.expiresAt)
      .isEqualTo(0L)

Аналогичным образом можно переопределить обработчик `HTTPException`.

Например, для этих ошибок можно вернуть обычный текстовый ответ вместо JSON:

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Технические детали"
    Можно также использовать `from starlette.responses import PlainTextResponse`.

Do mesmo modo, você pode sobreescrever o `HTTPException`.

Por exemplo, você pode querer retornar uma *response* em *plain text* ao invés de um JSON para os seguintes erros:

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Detalhes Técnicos"
    Você pode usar `from starlette.responses import PlainTextResponse`.

Genauso können Sie den `HTTPException`-Handler überschreiben.

Zum Beispiel könnten Sie eine Klartext-Response statt JSON für diese Fehler zurückgeben wollen:

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Technische Details"
    Sie können auch `from starlette.responses import PlainTextResponse` verwenden.

## Evoluindo o Exemplo

Agora modifique o arquivo `main.py` para receber um corpo para uma requisição `PUT`.

Declare o corpo utilizando tipos padrão Python, graças ao Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float

Şimdi `main.py` dosyasını, `PUT` isteğiyle birlikte bir gövde alacak şekilde değiştirelim.

<abbr title="Gövde: Body">Gövde</abbr>yi Pydantic sayesinde standart python tiplerini kullanarak tanımlayalım.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float
