Python 为什么属性不能正常工作

我的程序有一个问题，即在输入中输入一个字母后，程序崩溃。任务要求我必须借助属性来控制数据是否正确。然而，好像程序根本就不去那里。我知道，对int进行强制转换时，它将始终通过属性并在计数时抛出，但当它不投影时，它将无论如何抛出程序。请帮忙。这是我的密码：

 import math

    def distance_from_origin(self, x, y):
        odl = math.sqrt((0 - x) ** 2 + (0 - y) ** 2)
        return odl

因为属性具有相同的名称。不，它们没有，并且不在名称中是问题。问题在于输入..看，您有一个属性

x

。它是一个类属性，意味着它附加到类。现在，如果执行

self.x=…

，将创建am实例属性。它将对类上的属性进行阴影处理。这一行中有一个错误：

print（“与坐标轴中心的距离：”，round（p1.与原点的距离（x，y），2））

：x和y为undefined@Klaus我需要更改atributes类的名称？？？

def __init__(self, x, y):
        self._x = x
        self._y = y

    @property
    def x(self):
        return self.x

    @x.setter
    def x(self, x):

        if not isinstance(x, int):
            raise TypeError(f"{x} is not INT")
        self.x = x

    @property
    def y(self):
        return self.y

    @y.setter
    def y(self, y):
        if not isinstance(y, int):
            raise TypeError(f"{y} is not INT")
        self.y = y
