夨完夳一夬计算夲点间夰夦的夯序。 如： Enter point A(x, y):1,1 Enter point B(x, y):2,1 The distance between the pointA and the pointB is 1.0 .

好的，下面是 Python 代码实现：

import math

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y

def distance(point1, point2):
    return math.sqrt((point1.x - point2.x) ** 2 + (point1.y - point2.y) ** 2)

pointA = Point(*map(int, input("Enter point A(x, y):").split(",")))
pointB = Point(*map(int, input("Enter point B(x, y):").split(",")))

print("The distance between the pointA and the pointB is", distance(pointA, pointB), ".")

运行示例：

Enter point A(x, y):1,1
Enter point B(x, y):2,1
The distance between the pointA and the pointB is 1.0 .
