Déclarez ce corps en utilisant les types Python standards, grâce à Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float
    is_offer: Union[bool, None] = None


@app.get("/")

## 範例升級

現在繼續修改 `main.py` 檔案，來接收一個帶有 body 的 `PUT` 請求。

我們使用 Pydantic 來使用標準的 Python 型別聲明請求。
