python - '类型错误: __init__() got multiple values for argument' with Python 3 using super() function

Question

我正在使用继承的 Python 3 编写 OOP 程序，当我尝试像这样初始化子类时遇到标题错误:

class Parent:
    def __init__(self, var1, var2):
        self.var1 = var1
        self.var2 = var2

    #more methods that to some stuff

class Child(Parent):
    a = 1 #a and b are class attributes
    b = 2

    def __init__(self, var1 = 1, var2 = 2, var3 = None):
        super().__init__(self, var1 = 1, var2 = 2) #error shows up for this line
        self.var3 = var3

child_obj = Child(var3 = 3)

当我创建 Child 对象时，我收到一条错误消息:TypeError: __init__() gets multiple values for argument 'var1'。有人知道这里可能出了什么问题吗？提前致谢。

请检查您的代码是否有误。 你想要这样的东西吗？

class Parent:
    def __init__(self, var1, var2):
        self.var1 = var1
        self.var2 = var2
        print(var2)

    #more methods that to some stuff

class Child(Parent):
    a = 1 #a and b are class attributes
    b = 2

    def __init__(self, var1 = 1, var2 = 2, var3 = None):
        super().__init__(var1 = 1, var2 = 2) 
        self.var3 = var3

child_obj = Child(var3 = 3)
