এখন `main.py` ফাইলটি পরিবর্তন করুন যেন এটি `PUT` রিকুয়েস্ট থেকে বডি পেতে পারে।

Python স্ট্যান্ডার্ড লাইব্রেরি, Pydantic এর সাহায্যে বডি ঘোষণা করুন।

```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("/")

  int copyIntoArray(@Nullable Object[] dst, int offset) {
    // this loop is faster for RandomAccess instances, which ImmutableLists are
    int size = size();
    for (int i = 0; i < size; i++) {
      dst[offset + i] = get(i);
    }
    return offset + size;
  }

  /**
   * Returns a view of this immutable list in reverse order. For example, {@code ImmutableList.of(1,

    }
  }

  private boolean hasInstanceMethodToTestNulls(Class<?> c, Visibility visibility) {
    for (Method method : nullPointerTester.getInstanceMethodsToTest(c, visibility)) {
      for (Parameter param : Invokable.from(method).getParameters()) {
        if (!NullPointerTester.isPrimitiveOrNullable(param)) {
          return true;
        }
      }
    }

Ahora modifica el archivo `main.py` para recibir un body desde un request `PUT`.

Declara el body usando tipos estándar de Python, gracias a Pydantic.
