Aquí, `new_dict` contendrá todos los pares clave-valor de `old_dict` más el nuevo par clave-valor:

```Python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```

    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

Hier wird `new_dict` alle Schlüssel-Wert-Paare von `old_dict` plus das neue Schlüssel-Wert-Paar enthalten:

```Python

    "old key": "old value",
    "second old key": "second old value",
