 2 class Dog:
 3     def Eat(self):
 4         print("Dog Eating...")
 5 class Son:
 6     def __init__(self):

 8     def Eat(self):
 9         print("Son Eating...")
10 class Father:
11     def LetSonEat(self,m):
12         if(isinstance(m,Son)):
13             m.Eat()
14             m.height=120
15         else:
16             print("You are not my son")
17 son=Son()
18 dog=Dog()
19 son2=copy.copy(son)
20 father=Father()
21 father.LetSonEat(son)
22 father.LetSonEat(dog)
23 print(son.height)
24 print(son2.height)
