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

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

Porque lo estamos pasando como un **valor a un argumento** en lugar de ponerlo en una **anotación de tipos**, tenemos que usar `Union` incluso en Python 3.10.

Si estuviera en una anotación de tipos podríamos haber usado la barra vertical, como:

```Python
{"id": id}
```

Örneğin ID değeri `42` ise, şu şekilde render edilir:

```html
Item ID: 42
```

### Template `url_for` Argümanları { #template-url-for-arguments }

Template içinde `url_for()` da kullanabilirsiniz; argüman olarak, *path operation function*'ınızın kullandığı argümanların aynısını alır.

Dolayısıyla şu bölüm:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

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

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

Dado que estamos passando-o como um **valor para um argumento** em vez de colocá-lo em uma **anotação de tipo**, precisamos usar `Union` mesmo no Python 3.10.

Se estivesse em uma anotação de tipo, poderíamos ter usado a barra vertical, como:

with `Annotated` would **not be affected** at all.

If you call those functions in **other places in your code**, the actual **default values** will be kept, your editor will help you notice missing **required arguments**, Python will require you to pass required arguments at **runtime**, you will be able to **use the same functions** for different things and with different libraries (e.g. **Typer** will soon support `Annotated` too, then you could use the same function for an API and a CLI),...
