python-設計並實現平面點類Point

【題目描述】定義一個平面點類Point，對其重載運算符關系運算符，關系運算以距離坐標原點的遠近作為基准，遠的為大。

程序完成對其的測試。
【練習要求】請給出源代碼程序和運行測試結果，源代碼程序要求添加必要的注釋。

 

代碼：

import math
class Point():
    def __init__(self,x,y):
        self.x = x
        self.y = y
    def __lt__(self, other):
        l1 = math.sqrt(self.x**2+self.y**2)
        l2 = math.sqrt(other.x**2+other.y**2)
        return l1<l2
    def __le__(self, other):
        l1 = math.sqrt(self.x**2+self.y**2)
