import copy
names = ["88xiaoming","liuhai","杨东","liuhai","xiaohuang","liuhai"]
names2 = copy.deepcopy(names)
print (names)
print(names2)
names[1] = "叶文"
names[5] = "一路向西"
print(names)
print(names2)

#copy的三种方法：
person = ['a',['b',180]]
p1 = copy.copy(person)
p2 = person[:]
p3 = list(person)
print (p1)
print (p2)
print (p3)
p1[0] = 'aaa'  #修改数据
print (p1)
p1[1][0] = 80
print (p1)
