super的用法是调用继承类的初始化方法，如下面的代码：

 1 class A(object):
 2     def __init__(self):
 3         print ‘A __init__‘
 4         super(A, self).__init__()
 5         print ‘leave A‘
 6
 7 class C(object):
 8     def __init__(self):
 9         print ‘C __init__‘
10         super(C, self).__init__()
11         print ‘leave C‘
12
13 class B(A,C):
14     def __init__(self):
15         print ‘B __init__‘
16         super(B, self).__init__()
17         print ‘leave B‘
18
19 class D(B):
20     def __init__(self):
21         print ‘D __init__‘
22         super(D, self).__init__()
23         print ‘leave D‘
24
25 if __name__ == ‘__main__‘:
26     D()

结果：

1 D __init__
2 B __init__
3 A __init__
4 C __init__
5 leave C
6 leave A
7 leave B
8 leave D
