【3.9】super真的是调用父类的方法? 

 1 #!/user/bin/env python
 2 # -*- coding:utf-8 -*-
 3 
 4 
 5 class A:
 6     def __init__(self):
 7         print('A')
 8 
 9 
10 class B(A):
11     def __init__(self):
12         print('B')
13         super().__init__()
14 
15 
16 class C(A):
17     def __init__(self):
18         print('C')
19         super().__init__()
20 
21 
22 class D(B, C):
23     def __init__(self):
24         print('D')
25         super().__init__()
26 
27 
28 if __name__ == '__main__':
29     print(D.__mro__)
30     d = D()

(<class '__main__.D'>, <class '__main__.B'>, <class '__main__.C'>, <class '__main__.A'>, <class 'object'>)

D
B
C
A

　　super其实是根据mro算法来调用的
