Chapter 4, Problem 3D

Explanation of Solution

Program:

from graphics import *

 # Defines the function named main()

def main():

    # Openstucts GraphWin object with "Graphics Window" default title and default size 200 x 200 pixels

    win = GraphWin()

    # Constructs a circle object with center Point object at 50,50 and radius of 20 pixels

    shape = Circle(Point(50,50),20)

    # Calls setOutline method of circle object named shape, seting its outline to the color red

    shape.setOutline("red")

    # Calls setFill method of circle object shape, it fills itself with the color red

    shape.setFill("red")

     # Calls draw method of circle object named shape, it draws itself in graphics window object named win

    shape.draw(win)

    # Creates a counted loop that will iterate 10 times

    for i in range(10):

        # Calls getMouse() method of graphics window object win

        p = win...
