딕셔너리
런타임에 딕셔너리 활용하기
대괄호 표기가 딕셔너리와 어떻게 작동하는지 알면 런타임에 딕셔너리를 어떻게 증가시킬 수
있는지 이해할 수 있습니다. 기존의 딕셔너리가 있다면 새로운 키를 대괄호 안에 넣고 객체를
할당해 키/값 쌍을 새로 추가할 수 있습니다.
예를 들어 다음은
person3
딕셔너리의 현재 상태를 보여줍니다. 이어서
Age
라는 키와 연관된
33
값의 새로운 쌍을 추가합니다. 그리고
person3
딕셔너리를 출력해 새로운 행의 데이터가
성공적으로 추가되었는지 확인합니다.
>>> person3
{'Name': 'Ford Prefect', 'Gender': 'Male',
'Home Planet': 'Betelgeuse Seven',
'Occupation': 'Researcher'}
