* `Optional`
* ...등등

위와 같은 타입은 **Generic(제네릭) 타입** 혹은 **Generics(제네릭스)**라고 불립니다.

### 타입으로서의 클래스

변수의 타입으로 클래스를 선언할 수도 있습니다.

이름(name)을 가진 `Person` 클래스가 있다고 해봅시다.

{* ../../docs_src/python_types/tutorial010.py hl[1:3] *}


그렇게 하면 변수를 `Person`이라고 선언할 수 있게 됩니다.

그리고 역시나 모든 에디터 도움을 받게 되겠죠.

Karena parameter path `item_id` bernilai `"foo"` yang bukan tipe data `int`.
