Python之拷贝对象

import copy a = [1, 2, 3, 4, ['a', 'b']] #原始对象 b = a #赋值，传对象的引用 c = copy.copy(a) #对象拷贝，浅拷贝 只拷贝父对象 子对象为引用 d = copy.deepcopy(a) #对象拷贝，深拷贝 拷贝对象及其子对象 a.append(5) #修改对象a a[4].append('c') #修改对象a中的['a', 'b']数组对象 print('a = ', a) print('b = ', b) print('c = ', c) print('d = ', d) a = [1, 2, 3, 4, ['a', 'b', 'c'], 5] b = [1, 2, 3, 4, ['a', 'b', 'c'], 5] c = [1, 2, 3, 4, ['a', 'b', 'c']] d = [1, 2, 3, 4, ['a', 'b']]
