在Zelle graphics.py中绘制多边形后无法显示坐标

Question

Am able to successfully draw a polygon using Zelle graphics.py in Python, but I was unable to display the coordinates for the points used. How can I get it done using getPoints() only.

Here's my code:

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()

You can simply do that with print(polygon.getPoints()) in your main method, which gives you [Point(60.0, 80.0), Point(50.0, 70.0), Point(70.0, 20.0), Point(90.0, 50.0), Point(100.0, 80.0)] as output.

Example code:

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()
