구조화된 데이터
내장 자료구조 결합하기
지금까지 자료구조를 살펴보면서 궁금한
점이 있었는데요, 더 복잡한 자료구조도 만들
수 있는 건가요? 예를 들면 딕셔너리에
딕셔너리를 저장할 수도 있는 거죠?
많은 사람이 묻는 질문입니다.
보통 프로그래머가 숫자, 문자열, 불린을 리스트와
딕셔너리에 저장해보고 난 다음에는 내장 자료구조로 좀 더
복잡한 데이터를 저장할 수 있는지 궁금해 하기 시작합니다.
즉,
‘
내장 자료구조에 다른 내장 자료구조를 저장할 수
있는지?
’
같은 질문을 합니다.
대답은
‘
네
’
입니다. 이미 설명했듯이 파이썬에서는 모든 것이
객체이기 때문에 그렇습니다.
지금까지 내장 자료구조에 저장한 것은 모두 객체였습니다.
좀 더 정확히 표현하면 숫자나 문자열 같은 ‘단순
객체’였는데 내장 자료구조에는 사실 모든 객체를 저장할
수 있습니다. 모든 내장 자료구조도 (비록 복잡하지만)
객체입니다. 따라서 누굴 어디에 저장하든 마음대로 할
수 있어요. 그냥 단순 객체를 저장하듯이 내장 자료구조를
저장하세요. 그러면 됩니다.
딕셔너리의 딕셔너리 예제를 살펴봅시다.
지금까지 설명한 내용은 딕셔너리에만 적용되나요? 그러니까 리스트의 리스트, 리스트의 집합, 딕셔너리의 튜플 등도 가능한가요?
그렇습니다. 잠시 후에 딕셔너리의 딕셔너리 예제를 ...
