python super继承用法

 1 # 1，普通继承
 2 #新建一个父类
 3 class Father():
 4     def father(self,message):
 5         print(message)
 6 
 7 #子类继承父类
 8 class Child(Father):
 9     def child(self,message):
10         Father.father(self,message)
11 
12 c = Child()
13 c.child("sss")
14 #以上子类继承父类的做法有一定缺陷，付过修改父类名称，那么子类也要多处修改，
15 #因此引入super()类。
16 print("=============================")
17 # 2，super继承
18 class Animal(object):
19     def __init__(self,name):
20         self.name = name
21     def greet(self):
22         print(self.name,"is wang wang!")
23 a = Animal("Animal")
24 a.greet()
25 
26 class Dog(Animal):
27     def bark(self):
28         super().greet()
29 dog = Dog("Dog")
30 dog.bark()
