### Eine `list`e mit einem Typ-Parameter deklarieren

Um Typen wie `list`, `dict`, `tuple` mit inneren Typ-Parametern (inneren Typen) zu deklarieren:

* Wenn Sie eine Python-Version kleiner als 3.9 verwenden, importieren Sie das Äquivalent zum entsprechenden Typ vom `typing`-Modul

```

!!! tip
    `{"name", "description"}` 语法创建一个具有这两个值的 `set`。

    等同于 `set(["name", "description"])`。

#### 使用 `list` 而不是 `set`

如果你忘记使用 `set` 而是使用 `list` 或 `tuple`，FastAPI 仍会将其转换为 `set` 并且正常工作：

```Python hl_lines="31  37"
{!../../../docs_src/response_model/tutorial006.py!}
```

## 总结

使用*路径操作装饰器*的 `response_model` 参数来定义响应模型，特别是确保私有数据被过滤掉。

#### `Tuple` ve `Set`

`Tuple` ve `set`lerin tiplerini bildirmek için de aynısını yapıyoruz:

```Python hl_lines="1  4"
{!../../../docs_src/python_types/tutorial007.py!}
```

Bu şu anlama geliyor:

* `items_t` değişkeni sırasıyla `int`, `int`, ve `str` tiplerinden oluşan bir `tuple` türündedir .

E, ainda assim, o editor sabe que é um `str` e fornece suporte para isso.

#### `Tuple` e `Set`

Você faria o mesmo para declarar `tuple`s e `set`s:

```Python hl_lines="1 4"
{!../../../docs_src/python_types/tutorial007.py!}
```

Isso significa que:

* A variável `items_t` é uma `tuple` com 3 itens, um `int`, outro `int` e uma `str`.
