我不明白为什么我的 super() 会产生错误

Question

如果我这样编码，为什么我的程序可以工作：

class Shape:

    class Shape:
    shape_type = ""

    def __init__(self, c='*'):
        self.color = c

class Square(Shape):
    shape_type = "Quadrat"

    def __init__(self, w, *args, **kwargs):
        Shape.__init__(self, *args, **kwargs)
        self._width = w

q1 = Square(4, c="#")

但如果我使用 super() 函数则不会

class Shape:
    shape_type = ""

    def __init__(self, c='*'):
        self.color = c

class Square(Shape):
    shape_type = "Quadrat"

    def __init__(self, w, *args, **kwargs):
        super().__init__(self, *args, **kwargs)
        self._width = w

q1 = Square(4, c="#")

它说 TypeError: init() got multiple values for argument 'c'.

Answer 1

移除self:

class Shape:
    shape_type = ""

    def __init__(self, c='*'):
        self.color = c

class Square(Shape):
    shape_type = "Quadrat"

    def __init__(self, w, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self._width = w

q1 = Square(4, c="#")

使用 super() 时，您不必提供 self 参数，因为您是在实例上执行 __init__，而不是 class .

我不明白为什么我的 super() 会产生错误

i dont understand why my super() is producing an error

python

arguments

class

object

super
