1. 说明:

1. 共有两个.py文件,分别为Point.py和TestPoint.py
2. 两个文件位于相同的文件夹下

2. 文件Point.py :

import math

class Point:
    def reset(self):
        self.x=0
        self.y=0

    def move(self,x,y):
        self.x = x
        self.y = y

    def calculate_distance(self,otherPoint):
        d_x = otherPoint.x - self.x
        d_y = otherPoint.y - self.y
        #计算两点之间的距离
        distance = math.sqrt(d_x**2 + d_y**2)
        return distance

3. 文件TestPoint.py :

#调用Point.py文件中类Point
#from Point import Point
# p1 = Point()
# p2 = Point()

#导入Point类
import Point

p1 = Point.Point()
p2 = Point.Point()

p1.reset()
p2.move(6,8)

distan = p1.calculate_distance(p2)
print('两点之间的距离为',distan)

输出结果:

D:\python_project\venv\Scripts\python.exe D:/python_project/TestPoint.py
两点之间的距离为 10.0
