**FastAPI** calls the `CommonQueryParams` class. This creates an "instance" of that class and the instance will be passed as the parameter `commons` to your function.

## Type annotation vs `Depends`

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

//// tab | Python 3.8+

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

////

//// tab | Python 3.8+ non-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)]
```

////

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

## 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** 调用 `CommonQueryParams` 类。这将创建该类的一个 "实例"，该实例将作为参数 `commons` 被传递给你的函数。

## 类型注解 vs `Depends`

注意，我们在上面的代码中编写了两次`CommonQueryParams`：

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

最后的 `CommonQueryParams`:

```Python
... = Depends(CommonQueryParams)
```
