本例中有 3 个查询参数：

* `needy`，必选的 `str` 类型参数
* `skip`，默认值为 `0` 的 `int` 类型参数
* `limit`，可选的 `int` 类型参数

/// tip | "提示"

还可以像在[路径参数](path-params.md#_8){.internal-link target=_blank} 中那样使用 `Enum`。

Das bedeutet:

* Die Variable `items_t` ist ein `tuple` mit 3 Elementen, einem `int`, einem weiteren `int` und einem `str`.
* Die Variable `items_s` ist ein `set`, und jedes seiner Elemente ist vom Typ `bytes`.

#### Dict

Um ein `dict` zu definieren, übergeben Sie zwei Typ-Parameter, getrennt durch Kommas.

Finally, the identity of our heroes is protected! 🥷

It also re-declares `id: int`. By doing this, we are making a **contract** with the API clients, so that they can always expect the `id` to be there and to be an `int` (it will never be `None`).

/// tip

Having the return model ensure that a value is always available and always `int` (not `None`) is very useful for the API clients, they can write much simpler code having this certainty.
