E a especificação diz que os campos devem ser nomeados assim. Portanto, `user-name` ou `email` não funcionariam.

Mas não se preocupe, você pode mostrá-lo como quiser aos usuários finais no frontend.

E seus modelos de banco de dados podem usar qualquer outro nome que você desejar.

## Alias parameters

Imagine that you want the parameter to be `item-query`.

Like in:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

But `item-query` is not a valid Python variable name.

The closest would be `item_query`.

But you still need it to be exactly `item-query`...

Then you can declare an `alias`, and that alias is what will be used to find the parameter value:

    // ===================================================================================
    //                                                                       Name Override
    //                                                                       =============
    @Override
    public String asTableDbName() {
        return "elevate_word_to_label";
    }

    @Override

```

这表示：

* 变量 `prices` 是一个 `dict`：
    * 这个 `dict` 的所有键为 `str` 类型（可以看作是字典内每个元素的名称）。
    * 这个 `dict` 的所有值为 `float` 类型（可以看作是字典内每个元素的价格）。

### 类作为类型

你也可以将类声明为变量的类型。

假设你有一个名为 `Person` 的类，拥有 name 属性：

```Python hl_lines="1-3"
{!../../docs_src/python_types/tutorial010.py!}
```

接下来，你可以将一个变量声明为 `Person` 类型：

```Python hl_lines="6"
{!../../docs_src/python_types/tutorial010.py!}
```

`cluster/saltbase/salt/kube-dns`, i.e. `cluster/saltbase/salt/kube-dns/{skydns-rc.yaml.base,skydns-rc.yaml.in}`, either substitute one of `__PILLAR__FEDERATIONS__DOMAIN__MAP__` or `{{ pillar['federations_domain_map'] }}` with the corresponding federation name to domain name value or remove them if you do not support cluster federation at this time. If you plan to substitute the parameter with its value, here is an example for `{{ pillar['federations_domain_map'] }}` ([#28132](https://github.com/kubernetes/kubernetes/pull/28132),...
