 1 import copy
 2 #names = "jessie jack serena sally eden"
 3 names = ["jeessie","jacker","serrena",["jeesie","saily"],"edeen"]
 4 name2 = copy.copy(names)
 5 print(names)
 6 print(name2)
 7 names[2] = "小敏"
 8 names[3][0] = "JEESSIE"
 9 print(names)
10 print(name2)

['jeessie', 'jacker', 'serrena', ['jeesie', 'saily'], 'edeen']
['jeessie', 'jacker', 'serrena', ['jeesie', 'saily'], 'edeen']
['jeessie', 'jacker', '小敏', ['JEESSIE', 'saily'], 'edeen']
['jeessie', 'jacker', 'serrena', ['JEESSIE', 'saily'], 'edeen']

比如说房间里有小明和小丽，小美知道这个信息后呢，就去这个房间(指针)了，这样，这个房间是不是有三个人了？

浅拷贝：就是把这个指针赋值一个变量，如果你对这个变量做操作，这条记录也会随之变化。

#edit for Kris_ma
import copy
#names = "jessie jack serena sally eden"
names = ["jeessie","jacker","serrena",["jeesie","saily"],"edeen"]
name2 = copy.deepcopy(names)
print(names)
print(name2)
names[2] = "小敏"
names[3][0] = "JEESSIE"
print(names)
print(name2)
