Python3 super()和泛型类

#!/usr/bin/env python3

def generate_a(key):
    class A(object):
        def method(self):
            return {'key': key,}
    return A

BaseForB = generate_a(1337)

class B(BaseForB):
    def method(self):
        dict = super(BaseForB,self).method()
        dict.update({'other_key': 0,})
        return dict

EXPECTED = {'other_key': 0,'key': 1337,}
RESULT = B().method()

if EXPECTED == RESULT:
    print("Ok")
else:
    print("EXPECTED: ",EXPECTED)
    print("RESULT: ",RESULT)

这引起了：

AttributeError: 'super' object has no attribute 'method'

问题是 – 如何在B.method()中运行A.method()(我尝试用super()做的事情)

编辑

这是更合适的测试用例：

#!/usr/bin/env python3

def generate_a(key):
    class A(object):
        def method(self):
            return {'key': key,}
    return A

class B(object):
    def method(self):
        return {'key': 'thisiswrong',}

BaseForC = generate_a(1337)

class C(B,BaseForC):
    def method(self):
        dict = super(C,}
RESULT = C().method()

if EXPECTED == RESULT:
    print("Ok")
else:
    print("EXPECTED: ",RESULT)

问题是 – 我如何选择我感兴趣的哪个家长班？
