创建D的实例对象,结果为啥不是ABCD
class A(object): def __init__(self, a): print 'init A...' self.a = a class B(A): def __init__(self, a): super(B, self).__init__(a) print 'init B...' class C(A): def __init__(self, a): super(C, self).__init__(a) print 'init C...' class D(B, C): def __init__(self, a): super(D, self).__init__(a) print 'init D...'
