父类对象对子类对象方法的调用

import copy
class Dog:
    def Eat(self):
        print("Dog Eating...")
class Son:
    def __init__(self):
        self.height=100
    def Eat(self):
        print("Son Eating...")
class Father:
    def LetSonEat(self,m):
        if(isinstance(m,Son)):
            m.Eat()
            m.height=120
        else:
            print("You are not my son")
son=Son()
dog=Dog()
son2=copy.copy(son)
father=Father()
father.LetSonEat(son)
father.LetSonEat(dog)
print(son.height)
print(son2.height)

这是一个父类对象对子类对象的调用演示。“Son”对象数据可以采用引用及复制模式（copy）
