作业23

第一题

# 作业一：试验菱形问题下的属性查找顺序
class A:
    pass


class B(A):
    pass


class C(B):
    pass


class D(B):
    pass


class E(A):
    pass


class F(A):
    pass


class G(E):
    pass


class H(C, D, G, F):
    pass


class I(H):
    pass


class J(H):
    pass


# print(J.mro())
# print(H.mro())

第二题

Father不隐藏版

# 作业二：在昨天作业的基础之上
#    1、引入属性访问控制+property
#    2、引入继承与派生的概念来减少代码冗余
#       注意：要满足什么"是"什么的关系，不满足"是"的关系不要去继承
