多重继承的执行顺序,请解答以下输出结果是什么?并解释。 class A (object) : def __init__ (self) : print( 'A' ) super(A, self).__init__() class B (object) : def __init__ (self) : print( 'B' ) super(B, self).__init__() class C (A) : def __init__ (self) : print( 'C' ) super(C, self).__init__() class D (A) : def __init__ (self) : print( 'D' ) super(D, self).__init__() class E (B, C) : def __init__ (self) : print( 'E' ) super(E, self).__init__() class F (C, B, D) : def __init__ (self) : print( 'F' ) super(F, self).__init__() class G (D, B) : def __init__ (self) : print( 'G' ) super(G, self).__init__() if __name__ == '__main__' : g = G() f = F()
