Chapter 7, Problem 16PE

Program Plan Intro

Program to displays the score with each click and the total score in series

Program plan:

• Import the required packages
• In the “main()” function,
  • Create the object of “GraphWin()”.
  • Set the coordinates by calling the function “setCoords()”
  • Create an object named “c” and store the points
  • The outline of the circle is set to “green4” color.
  • The circle is filled with “white” color.
  • The width of the circle is set with the use of function “setWidth()”.
  • Draw the circle with the use of function “draw()”.
  • Create an object named “c2” and store the points
  • The outline of the circle is set to “green4” color.
  • The circle is filled with “red” color.
  • The width of the circle is set with the use of function “setWidth()”.
  • Draw the circle with the use of function “draw()”.
  • Create an object named “c3” and store the points
  • The outline of the circle is set to “green4” color.
  • The circle is filled with “blue” color.
  • The width of the circle is set with the use of function “setWidth()”.
  • Draw the circle with the use of function “draw()”.
  • Create an object named “c4” and store the points
  • The outline of the circle is set to “green4” color.
  • The circle is filled with “black” color.
  • The width of the circle is set with the use of function “setWidth()”.
  • Draw the circle with the use of function “draw()”.
  • Create an object named “c5” and store the points
  • The outline of the circle is set to “green4” color.
  • The circle is filled with “white” color.
  • The width of the circle is set with the use of function “setWidth()”.
  • Draw the circle with the use of function “draw()”.
  • Initialize a for loop to get the value of the points.
    • Get the points where the mouse is clicked and store it in variable “arrow”.
    • Derive the x-coordinate with the use of “getX()” function.
    • Derive the x-coordinate with the use of “getY()” function.
    • Calculate the value derived out of the equation and store in “z”.
    • If the z-value is less than or equal to 5 and greater than 4 then,
      • “y” is assigned with “1”
      • “sum” is added with the value of “y”.
    • If the z-value is less than or equal to 4 and greater than 3 then,
      • “y” is assigned with “3”
      • “sum” is added with the value of “y”.
    • If the z-value is less than or equal to 3 and greater than 2 then,
      • “y” is assigned with “5”
      • “sum” is added with the value of “y”.
    • If the z-value is less than or equal to 2 and greater than 1 then,
      • “y” is assigned with “7”
      • “sum” is added with the value of “y”.
    • If the z-value is less than 1 then,
      • “y” is assigned with “9”
      • “sum” is added with the value of “y”.
    • otherwise,
      • “y” is assigned with “0”
      • print the output statement.
      • Print the value stored in “y” and “sum”.
• Call the function “main()”.

Program Description Answer

This program displays score achieved with each click in an archery board and also calculates and displays the sum of the entire series of outputs.

Explanation of Solution

Program:

#import the required packages

from graphics import *

import math as m

#define the main() function

def main():

    #declare the required variables

    win = GraphWin()

    #set the coordinates

    win.setCoords(-5, -5, 5, 5)

    #draw the circle with specified points

    c = Circle(Point(0,0), 5)

    #set the outline of the circle

    c.setOutline("green4")

    #fill the circle with the colour

    c.setFill("white")

    #set the width of the circle

    c.setWidth(1)

    #draw the circle

    c.draw(win)

    #draw the circle with specified points

    c2 = Circle(Point(0,0), 4)

    #set the outline of the circle

    c2.setOutline("green4")

    #fill the circle with the colour

    c2.setFill("red")

    #set the width of the circle

    c2.setWidth(1)

    #draw the circle

    c2.draw(win)

    #draw the circle with specified points

    c3 = Circle(Point(0,0), 3)

    #set the outline of the circle

    c3.setOutline("green4")

    #fill the circle with the colour

    c3.setFill("blue")

    #set the width of the circle

    c3.setWidth(1)

    #draw the circle

    c3.draw(win)

    #draw the circle with specified points

    c4 = Circle(Point(0,0), 2)

    #set the outline of the circle

    c4.setOutline("green4")

    #fill the circle with the colour

    c4.setFill("black")

    #set the width of the circle

    c4.setWidth(1)

    #draw the circle

    c4.draw(win)

    #draw the circle with specified points

    c5 = Circle(Point(0,0), 1)

    #set the outline of the circle

    c5.setOutline("green4")

    #fill the circle with the colour

    c5.setFill("white")

    #set the width of the circle

    c5.setWidth(1)

    #draw the circle

    c5.draw(win)

    #declare and initialize the variable

    sum = 0

    #initialize the loop for x less than 5

    for x in range (5):

        #get the locations where mouse is clicked

        arrow = win.getMouse()

        #stores the X coordinate

        x = arrow.getX()

        #stores the Y coordinate

        y = arrow.getY()

        #calculate and store the value

        z = m.sqrt(x ** 2 + y ** 2)

        #condition for z to be less than or equal to 5 and greater than 4

        if 5 >= z > 4:

            #declare the variable

            y = 1

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than or equal to 4 and greater than 3   

        elif 4 >= z > 3:

            #declare the variable

            y = 3

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than or equal to 3 and greater than 2      

        elif 3 >= z > 2:

            #declare the variable

            y = 5

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than or equal to 2 and greater than 1      

        elif 2 >= z > 1:

            #declare the variable

            y = 7

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than 1     

        elif 1 > z:

            #declare the variable

            y = 9

            #calculate the value of sum

            sum = y + sum

        #else statement   

        else:

           #declare the variable

            y = 0

            #print the statement

            print("You missed!")

        #print the statement

        print("Point: {0}    Total: {1}".format(y, sum))

#call the main() function
