### `Union` in Python 3.10 { #union-in-python-3-10 }

In this example we pass `Union[PlaneItem, CarItem]` as the value of the argument `response_model`.

### `Union` en Python 3.10 { #union-in-python-3-10 }

En este ejemplo pasamos `Union[PlaneItem, CarItem]` como el valor del argumento `response_model`.

from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class BaseItem(BaseModel):
    description: str
    type: str


class CarItem(BaseItem):
    type: str = "car"


class PlaneItem(BaseItem):
    type: str = "plane"
    size: int


items = {
    "item1": {"description": "All my friends drive a low rider", "type": "car"},
    "item2": {

### `Union` in Python 3.10 { #union-in-python-3-10 }

In diesem Beispiel übergeben wir `Union[PlaneItem, CarItem]` als Wert des Arguments `response_model`.

### `Union` в Python 3.10 { #union-in-python-3-10 }

В этом примере мы передаём `Union[PlaneItem, CarItem]` в качестве значения аргумента `response_model`.

### `Union` no Python 3.10 { #union-in-python-3-10 }

Neste exemplo, passamos `Union[PlaneItem, CarItem]` como o valor do argumento `response_model`.
