<mxPoint x="-40" y="290"/>
                        </Array>
                    </mxGeometry>
                </mxCell>
                <mxCell id="49" value="" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;fillColor=#fff2cc;strokeColor=#d6b656;" parent="1" vertex="1">

## Evoluindo o Exemplo

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

Declare o corpo utilizando tipos padrão Python, graças ao 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

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()


class Item(BaseModel):
    name: str
    price: float

                        <Array as="points">
                            <mxPoint x="245" y="710"/>
                        </Array>
                    </mxGeometry>
                </mxCell>
                <mxCell id="49" value="" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;fillColor=#fff2cc;strokeColor=#d6b656;" parent="1" vertex="1">
                    <mxGeometry x="510" y="400" width="310" height="320" as="geometry"/>

## Nâng cấp ví dụ

Bây giờ sửa tệp tin `main.py` để nhận body từ một request `PUT`.

Định nghĩa của body sử dụng kiểu dữ liệu chuẩn của Python, cảm ơn 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

                            <mxPoint x="-40" y="290"/>
                        </Array>
                    </mxGeometry>
                </mxCell>
                <mxCell id="49" value="" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;fillColor=#fff2cc;strokeColor=#d6b656;" parent="1" vertex="1">
                    <mxGeometry x="510" y="400" width="310" height="320" as="geometry"/>
