আপনি সেটি আধুনিক পাইথনের সাথে করেন।

আপনাকে নতুন করে নির্দিষ্ট কোন লাইব্রেরির বাক্য গঠন, ফাংশন বা ক্লাস কিছুই শিখতে হচ্ছে না।

শুধুই আধুনিক **Python 3.6+**

উদাহরণস্বরূপ, `int` এর জন্য:

```Python
item_id: int
```

অথবা আরও জটিল `Item` মডেলের জন্য:

```Python
item: Item
```

...এবং সেই একই ঘোষণার সাথে আপনি পাবেন:

- এডিটর সাহায্য, যেমন
  - সমাপ্তি।
  - ধরণ যাচাই

따라서, 만약 당신이 `something`(함수가 아닐 수도 있음) 객체를 가지고 있고,

```Python
something()
```

또는

```Python
something(some_argument, some_keyword_argument="foo")
```

상기와 같은 방식으로 "호출(실행)" 할 수 있다면 "호출 가능"이 됩니다.

## 의존성으로서의 클래스

파이썬 클래스의 인스턴스를 생성하기 위해 사용하는 것과 동일한 문법을 사용한다는 걸 알 수 있습니다.

예를 들어:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name

Eu testei várias ideias nos editores Python mais populares: PyCharm, VS Code, e editores baseados no Jedi.

Pela última <a href="https://www.jetbrains.com/research/python-developers-survey-2018/#development-tools" class="external-link" target="_blank">Pesquisa do Desenvolvedor Python</a>, isso cobre cerca de 80% dos usuários.

這一點，再加上 Python 是 **資料科學**、機器學習，尤其是深度學習的主要語言，讓 **FastAPI** 成為資料科學/機器學習 Web API 和應用程式（以及許多其他應用程式）的絕佳選擇。

## `async` 和 `await`

現代 Python 版本提供一種非常直觀的方式定義非同步程式碼。這使得它看起來就像正常的「順序」程式碼，並在適當的時機「等待」。

當某個操作需要等待才能回傳結果，並且支援這些新的 Python 特性時，你可以像這樣編寫程式碼：

```Python
burgers = await get_burgers(2)
```

Use standard Python types for all the attributes:

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}


The same as when declaring query parameters, when a model attribute has a default value, it is not required. Otherwise, it is required. Use `None` to make it just optional.

For example, this model above declares a JSON "`object`" (or Python `dict`) like:

```JSON
{
    "name": "Foo",
