// This implementation of the GET operation applies lambda functions and returns the

Aber wenn wir das in der Zuweisung `response_model=PlaneItem | CarItem` machen, würden wir einen Fehler erhalten, weil Python versuchen würde, eine **ungültige Operation** zwischen `PlaneItem` und `CarItem` auszuführen, anstatt es als Typannotation zu interpretieren.

Auf die gleiche Weise können Sie Responses von Listen von Objekten deklarieren.

# Модель відповіді — Тип, що повертається

Ви можете оголосити тип, який використовуватиметься у відповіді, за допомогою *анотації типу, що повертається* *функцією операцією шляху* (path operation)

**Анотацію типу** можна вказати так само як і для вхідних **параметрів** функції: це можуть бути моделі Pydantic, списки (lists), словники (dictionaries), скалярні значення, як-от цілі числа (integers), булеві значення (booleans) тощо.
