### `StreamingResponse` { #streamingresponse }

Recebe um gerador assíncrono ou um gerador/iterador comum e retorna o corpo da resposta de forma contínua (stream).

Because the editor knows the types of the variables, you don't only get completion, you also get error checks:

Now you know that you have to fix it, convert `age` to a string with `str(age)`:

## Declaring types { #declaring-types }

Como o editor conhece os tipos de variáveis, você não obtém apenas o preenchimento automático, mas também as verificações de erro:

<img src="/img/python-types/image04.png">

Agora você sabe que precisa corrigí-lo, converta `age` em uma string com `str(age)`:

Porque el editor conoce los tipos de las variables, no solo obtienes autocompletado, también obtienes chequeo de errores:

Ahora sabes que debes corregirlo, convertir `age` a un string con `str(age)`:

Це означає:

* Змінна `items_t` це `tuple` з 3 елементами, `int`, ще `int`, та `str`.
* Змінна `items_s` це `set`, і кожен його елемент типу `bytes`.

#### Dict (словник)

Для возврата клиенту HTTP-ответов с ошибками используется `HTTPException`.

### Вызовите `HTTPException` в своем коде { #raise-an-httpexception-in-your-code }

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

#### *Enumerations-Wert* erhalten { #get-the-enumeration-value }

Den tatsächlichen Wert (in diesem Fall ein `str`) erhalten Sie via `model_name.value`, oder generell, `your_enum_member.value`:
