사전은 순서가 지정되지 않고 변경 가능하며 인덱싱되는 모음입니다. Python에서 사전은 중괄호로 작성되며 키와 값이 있습니다. copy() 메서드는 사전의 얕은 복사본을 반환합니다.
예
#creating a dictionary
original = {1:'vishesh', 2:'python'}
# copying using copy() function
new = original.copy()
# removing all elements from the list Only new list becomes empty as #copy() does shallow copy.
new.clear()
print('new: ', new)
print('original: ', original)
# between = and copy()
original = {1:'Vishesh', 2:'python'}
# copying using copy() function
new = original.copy()
# removing all elements from new list
# and printing both
new.clear()
print('new: ', new)
print('original: ', original)
original = {1:'one', 2:'two'}
# copying using =
new = original
# removing all elements from new list
# and printing both
new.clear()
print('new: ', new)
print('original: ', original) 출력
('new: ', {})
('original: ', {1: 'vishesh', 2: 'python'})
('new: ', {})
('original: ', {1: 'Vishesh', 2: 'python'})
('new: ', {})
('original: ', {})
