Here we are declaring a `UserIn` model, it will contain a plaintext password:

{* ../../docs_src/response_model/tutorial002_py310.py hl[7,9] *}

/// info

To use `EmailStr`, first install <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```Python hl_lines="3 5"
{
"name": "Bar",
"description": "The bartenders",
"price": 62,
"tax": 20.2
}
```

eles serão incluídos na resposta.

#### Dados com os mesmos valores que os padrões

Se os dados tiverem os mesmos valores que os padrões, como o item com ID `baz`:

```Python hl_lines="3 5-6"
{
"name": "Baz",
"description": None,

# functionality instead.
tfrun() { "$@"; }

if [[ $(uname -s) = MSYS_NT* ]]; then
  source ./ci/official/utilities/windows.sh
  echo 'Converting MSYS Linux-like paths to Windows paths (for Docker, Python, etc.)'
  source <(python ./ci/official/utilities/convert_msys_paths_to_win_paths.py --whitelist-prefix TFCI_)
fi

# Run all "tfrun" commands under Docker. See setup_docker.sh for details
if [[ "$TFCI_DOCKER_ENABLE" == 1 ]]; then

El `TestClient` está basado en <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, y afortunadamente, podemos usarlo directamente para probar la API.

## Ejemplo

///

Параметр `status_code` приймає число, яке відповідає HTTP коду статусу.

/// info | Інформація
`status_code` також може отримувати значення з `IntEnum`, наприклад, з Python <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

///

Він буде:

* Повертати вказаний код статусу у відповіді.

### Импортируйте `HTTPException`

{* ../../docs_src/handling_errors/tutorial001.py hl[1] *}

### Вызовите `HTTPException` в своем коде

`HTTPException` - это обычное исключение Python с дополнительными данными, актуальными для API.

Поскольку это исключение Python, то его не `возвращают`, а `вызывают`.
