Python 拷贝对象(深拷贝deepcopy与浅拷贝copy)

import copya = [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d = copy.deepcopy(a) #对象拷贝，深拷贝a.append(5) #修改对象aa[4].append('c') #修改对象a中的['a', 'b']数组对象print 'a = ', aprint 'b = ', bprint 'c = ', cprint 'd = ', d

 

 

输出结果：
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']]
