Pydantic sayəsində standart Python tiplərindən istifadə edərək <abbr title="Gövdə: Body ">gövdə</abbr>ni müəyyən edək.

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

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

    is_offer: Union[bool, None] = None


@app.get("/")

Agora modifique o arquivo `main.py` para receber um corpo para uma requisição `PUT`.

Declare o corpo utilizando tipos padrão Python, graças ao Pydantic.
