## Аннотация типа или `Depends`

Обратите внимание, что в приведенном выше коде мы два раза пишем `CommonQueryParams`:

//// tab | Python 3.6+ без Annotated

/// tip | Подсказка

Рекомендуется использовать версию с `Annotated` если возможно.

///

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

**FastAPI** llama a la clase `CommonQueryParams`. Esto crea una "instance" de esa clase y la instance será pasada como el parámetro `commons` a tu función.

## Anotación de tipos vs `Depends`

Nota cómo escribimos `CommonQueryParams` dos veces en el código anterior:

//// tab | Python 3.8+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.8+ sin `Annotated`

**FastAPI** ruft die Klasse `CommonQueryParams` auf. Dadurch wird eine „Instanz“ dieser Klasse erstellt und die Instanz wird als Parameter `commons` an Ihre Funktion überreicht.

## Typannotation vs. `Depends`

Beachten Sie, wie wir `CommonQueryParams` im obigen Code zweimal schreiben:

//// tab | Python 3.8+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.8+ nicht annotiert

		</dependency>
		<dependency>
			<groupId>commons-codec</groupId>
			<artifactId>commons-codec</artifactId>
			<version>${commons.codec.version}</version>
		</dependency>
		<dependency>
			<groupId>commons-io</groupId>
			<artifactId>commons-io</artifactId>
			<version>${commons.io.version}</version>
		</dependency>
		<dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-lang3</artifactId>

## Type annotation vs `Depends` { #type-annotation-vs-depends }

Notice how we write `CommonQueryParams` twice in the above code:

//// tab | Python 3.8+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

O **FastAPI** chama a classe `CommonQueryParams`. Isso cria uma "instância" dessa classe e é a instância que será passada para o parâmetro `commons` na sua função.

## Anotações de Tipo vs `Depends`

Perceba como escrevemos `CommonQueryParams` duas vezes no código abaixo:

//// tab | Python 3.8+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.8+ non-Annotated
