当你使用 `Query` 显式地定义查询参数时，你还可以声明它去接收一组值，或换句话来说，接收多个值。

例如，要声明一个可在 URL 中出现多次的查询参数 `q`，你可以这样写：

{* ../../docs_src/query_params_str_validations/tutorial011.py hl[9] *}

然后，输入如下网址：

```
http://localhost:8000/items/?q=foo&q=bar
```

你会在*路径操作函数*的*函数参数* `q` 中以一个 Python `list` 的形式接收到*查询参数* `q` 的多个值（`foo` 和 `bar`）。

因此，该 URL 的响应将会是：

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

#### Случайный элемент { #a-random-item }

С помощью `data.items()` мы получаем <abbr title="Объект, по которому можно итерироваться циклом for, например список, множество и т. п.">итерируемый объект</abbr> с кортежами, содержащими ключ и значение для каждого элемента словаря.

Мы превращаем этот итерируемый объект в обычный `list` через `list(data.items())`.
