#### `Tuple`과 `Set`

`tuple`과 `set`도 동일하게 선언할 수 있습니다.

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial007.py!}
```

이 뜻은 아래와 같습니다:

* 변수 `items_t`는, 차례대로 `int`, `int`, `str`인 `tuple`이다.
* 변수 `items_s`는, 각 아이템이 `bytes`인 `set`이다.

#### `Dict`

`dict`를 선언하려면 컴마로 구분된 2개의 파라미터가 필요합니다.

첫 번째 매개변수는 `dict`의 키(key)이고,

두 번째 매개변수는  `dict`의 값(value)입니다.
