To declare those types and the internal types, you can use the standard Python module `typing`. It exists specifically to support these type hints.

#### Newer versions of Python

The syntax using `typing` is **compatible** with all versions, from Python 3.6 to the latest ones, including Python 3.9, Python 3.10, etc.

### Generische Typen mit Typ-Parametern

Es gibt Datenstrukturen, die andere Werte enthalten können, wie etwa `dict`, `list`, `set` und `tuple`. Die inneren Werte können auch ihren eigenen Typ haben.

Diese Typen mit inneren Typen werden „**generische**“ Typen genannt. Es ist möglich, sie mit ihren inneren Typen zu deklarieren.

import typing

from fastapi import FastAPI
from fastapi.responses import JSONResponse
from fastapi.testclient import TestClient
from pydantic import BaseModel

app = FastAPI()


class JsonApiResponse(JSONResponse):
    media_type = "application/vnd.api+json"


class Error(BaseModel):
    status: str
    title: str


class JsonApiError(BaseModel):
    errors: typing.List[Error]


@app.get(
    "/a/{id}",

Para declarar esses tipos e os tipos internos, você pode usar o módulo Python padrão `typing`. Ele existe especificamente para suportar esses type hints.

#### Versões mais recentes do Python

A sintaxe utilizando `typing` é **compatível** com todas as versões, desde o Python 3.6 até as últimas, incluindo o Python 3.9, 3.10, etc.

It will be defined in OpenAPI with `anyOf`.

To do that, use the standard Python type hint <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

## `Union` 或者 `anyOf`

响应可以声明为两种类型的 `Union` 类型，即该响应可以是两种类型中的任意类型。

在 OpenAPI 中可以使用 `anyOf` 定义。

为此，请使用 Python 标准类型提示 <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>：

Để khai báo những kiểu dữ liệu và những kiểu dữ liệu nội bộ đó, bạn có thể sử dụng mô đun chuẩn của Python là `typing`. Nó có hỗ trợ những gợi ý kiểu dữ liệu này.

#### Những phiên bản mới hơn của Python

Cú pháp sử dụng `typing` **tương thích** với tất cả các phiên bản, từ Python 3.6 tới những phiên bản cuối cùng, bao gồm Python 3.9, Python 3.10,...

এই টাইপগুলি এবং অভ্যন্তরীণ টাইপগুলি ঘোষণা করতে, আপনি Python মডিউল `typing` ব্যবহার করতে পারেন। এটি বিশেষভাবে এই টাইপ হিন্টগুলি সমর্থন করার জন্য রয়েছে।

#### Python এর নতুন সংস্করণ

`typing` ব্যবহার করা সিনট্যাক্সটি Python 3.6 থেকে সর্বশেষ সংস্করণগুলি পর্যন্ত, অর্থাৎ Python 3.9, Python 3.10 ইত্যাদি সহ সকল সংস্করণের সাথে **সামঞ্জস্যপূর্ণ**।

Он будет определён в OpenAPI как `anyOf`.

Для этого используйте стандартные аннотации типов в Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:
