super()函数调用父类方法一直报错,代码全程按照教程来的

Question

按照教程写类继承的代码,但是一直结果报错,代码如下 比较简单

class father(object):
    def __init__(self, attribute_value1, attribute_value2):
        self.attribute1 = attribute_value1
        self.attribute2 = attribute_value2

    def __str__(self):
        return "\"父类father\""

    def __del__(self):
        return "已删除%s" % (father.__str__(self))

    def testFunction(self, parameter1, parameter2):
        return f"{father.__str__(self)}的属性值是{self.attribute1}和{self.attribute2},参数是{parameter1}和{parameter2}"


class son(father):
    def __init__(self):
        super(father, self).__init__()
        self.attribute1, self.attribute2 = "1", 2

    def __str__(self):
        return "子类son"

    def __del__(self):
        return "已删除%s" % (son.__str__(self))

    def old_method(self):
        super(father, self).__init__()
        return super(father, self).testFunction()


result = son()
print(result.attribute2, result.attribute1)
print(result.old_method())

然后运行下来是报错,就是这个错误"AttributeError: 'super' object has no attribute '"

我检查了好几遍缩进的情况,也在网上查了,没找到解决办法

请问有没有办法能解决啊 感谢各位

Answer 1

super(father, self)
改为
super(son, self)
