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

첫 번째 매개변수는 `dict`의 키(key)이고,

두 번째 매개변수는  `dict`의 값(value)입니다.

{* ../../docs_src/python_types/tutorial008.py hl[1,4] *}


이 뜻은 아래와 같습니다:

* 변수 `prices`는 `dict`이다:
    * `dict`의 키(key)는 `str`타입이다. (각 아이템의 이름(name))
    * `dict`의 값(value)는 `float`타입이다. (각 아이템의 가격(price))
