Python 无法在Zelle graphics.py中绘制多边形后显示坐标

我能够在Python中使用Zelle graphics.py成功地绘制多边形，但无法显示所用点的坐标。如何仅使用getPoints（）完成此操作

这是我的密码：

import math
import graphics #must be included
from graphics import* # must be included

def main():
    win = graphics.GraphWin("Exercise 2, Polygon", 500, 500)
    #denotes window size

    win.setBackground("black")

    polygon = Polygon(Point(60,80),Point(50,70),Point(70,20),Point(90,50),Point(100,80))
    #Include "Point" in the statement, else it wouldn't work
    polygon.setOutline("yellow")
    polygon.setWidth(5)
    polygon.draw(win)


main()

---

您只需在main方法中使用

print（polygon.getPoints（））

即可，该方法将

[点（60.0,80.0）、点（50.0,70.0）、点（70.0,20.0）、点（90.0,50.0）、点（100.0,80.0）]

作为输出

示例代码：

import math
import graphics #must be included
from graphics import* # must be included

def main():
    win = graphics.GraphWin("Exercise 2, Polygon", 500, 500)
    #denotes window size

    win.setBackground("black")

    polygon = Polygon(Point(60,80),Point(50,70),Point(70,20),Point(90,50),Point(100,80))
    #Include "Point" in the statement, else it wouldn't work
    polygon.setOutline("yellow")
    polygon.setWidth(5)
    polygon.draw(win)

    print(polygon.getPoints())    

main()
