Python: 练习 深拷贝和浅拷贝

from copy import copy, deepcopy

a_1 = [1, ["a", "b"]]
a_2 = a_1.copy()
print(id(a_1), id(a_1[0]), id(a_1[1]))
print(id(a_2), id(a_2[0]), id(a_2[1]))
print("*" * 20)
# 浅拷贝
a_1 = [1, ["a", "b"]]
a_2 = copy(a_1)
print(id(a_1), id(a_1[0]), id(a_1[1]))
print(id(a_2), id(a_2[0]), id(a_2[1]))
print("*" * 20)
# 深拷贝
a_1 = [1, ["a", "b"]]
a_2 = deepcopy(a_1)
print(id(a_1), id(a_1[0]), id(a_1[1]))
print(id(a_2), id(a_2[0]), id(a_2[1]))
