初学者写python之三坐标点是否构成三角形

要求：用户输入直角坐标系的三个坐标点，判断是否构成三角形，程序若出现错误，则抛出异常

import math


class Zuobiao:
    def __init__(self, Ax, Ay, Bx, By, Cx, Cy):
        self.Ax = Ax
        self.Ay = Ay
        self.Bx = Bx
        self.By = By
        self.Cx = Cx
        self.Cy = Cy

        self.abnum = (self.Ax - self.Bx) ** 2 + (self.Ay - self.By) ** 2
        self.ablen = math.sqrt(self.abnum)  # ab长度
        self.acnum = (self.Ax - self.Cx) ** 2 + (self.Ay - self.Cy) ** 2
        self.aclen = math.sqrt(self.acnum)  # ac长度
        self.bcnum = (self.Bx - self.Cx) ** 2 + (self.By - self.Cy) ** 2
        self.bclen = math.sqrt(self.bcnum)  # bc长度

    def judge(self):
        if self.Ax != self.Bx != self.Cx and self.Ay != self.By != self.Cy:
            if self.ablen == self.aclen == self.bclen:
                print('此三点能构成三角形，并且为等边三角形')
        elif self.ablen + self.aclen > self.bclen > self.ablen - self.aclen:
            print('此三点能构成三角形')
        else:
            print('此三点不能构成三角形')

try:
    a,b = map(int,input("请输入a点坐标,且以','分割:").split(','))
    c,d = map(int,input("请输入b点坐标,且以','分割:").split(','))
    e,f = map(int,input("请输入c点坐标,且以','分割:").split(','))
    zuobiao = Zuobiao(a,b,c,d,e,f)      # 输入各个坐标
    print(zuobiao.judge())
except Exception as error:
    print('程序出现错误:',error)

运行结果：
