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    d = copy.deepcopy(a) #对象拷贝，深拷贝        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

 

 

输出为：

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']]
