### Предупреждение о замене

Это означает, что если вы хотите обновить элемент `bar`, используя `PUT` с телом, содержащим:

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

поскольку оно не включает уже сохраненный атрибут `"tax": 20.2`, входная модель примет значение по умолчанию `"tax": 10.5`.

non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the modifications to

You will get completion in code you might even consider impossible before. As for example, the `price` key inside a JSON body (that could have been nested) that comes from a request.

No more typing the wrong key names, coming back and forth between docs, or scrolling up and down to find if you finally used `username` or `user_name`.

![editor support](https://fastapi.tiangolo.com/img/pycharm-completion.png)

Você terá completação do seu código que você poderia considerar impossível antes. Como por exemplo, a chave `price` dentro do corpo JSON (que poderia ter sido aninhado) que vem de uma requisição.

你将能进行代码补全，这是在之前你可能曾认为不可能的事。例如，在来自请求 JSON 体（可能是嵌套的）中的键 `price`。

不会再输错键名，来回翻看文档，或者来回滚动寻找你最后使用的 `username` 或者 `user_name` 。



### 简洁

任何类型都有合理的**默认值**，任何和地方都有可选配置。所有的参数被微调，来满足你的需求，定义成你需要的 API。

但是默认情况下，一切都能**“顺利工作”**。
