题解 | 两点间距离

class Point:
    def __init__(self, a=0, b=0):
        self.x = a
        self.y = b
#
# 代码中的类名、方法名、参数名已经指定，请勿修改，直接返回方法规定的值即可
#
# 计算A点与B点之间的距离
# @param point_A Point类 A点
# @param point_B Point类 B点
# @return double浮点型
#
class Solution:
    def calculateDistance(self , point_A: Point, point_B: Point) -> float:
        # write code here
        dx = point_A.x - point_B.x
        dy = point_A.y - point_B.y

        distance = (dx ** 2 + dy ** 2) ** 0.5

        return distance
