- Check the condition.
  - Assign the “point2” to “true”.
- Otherwise, Assign the “point3” to “true”
- Activate all the three doors.
- Get the action mouse clicked.
- Check the condition using “while” loop.
  - Check the condition for selecting the door 1 to be clicked.
  - Check the condition for selecting the door 2 to be clicked.
  - Check the condition for selecting the door 3 to be clicked.
- Call the “getMouse()” function
Call the main function.

Program Plan Intro

Three Button Monte

Program Plan:

Import the required packages.
Declare a main function. Inside the main function,
- Create the application window.
- Draw the interface widget by creating three buttons.
- Assign the text to the interface.
- Call the method “draw()”.
- Get the random number.
- Assign the values to “false”.
- Check the condition.
  - Assign “point1” to “true”.
- Check the condition.
  - Assign the “point2” to “true”.
- Otherwise, Assign the “point3” to “true”
- Activate all the three doors.
- Get the action mouse clicked.
- Check the condition using “while” loop.
  - Check the condition for selecting the door 1 to be clicked.
  - Check the condition for selecting the door 2 to be clicked.
  - Check the condition for selecting the door 3 to be clicked.
- Call the “getMouse()” function
Call the main function.

Explanation of Solution

Program:

Refer the program “button.py” given in the “Chapter 10” from the text book. Add the method “update()” along with the given code.

#Define the method update

def update(self, win, label):

#Call the method undraw()

self.label.undraw()

#Assign the position to centre

center = self.center

#Assign the label

self.label = Text(center, label)

#Set active to false

self.active = False

#Call the method draw()

self.label.draw(win)

Main.py:

#Import the required packages

from button import Button

from graphics import GraphWin, Point, Text

from random import random

#Definition of main method

def main():

#Creating the application window by setting title, cords and background

win = GraphWin("Three Button Monte", 500, 300)

win.setCoords(-12, -12, 12, 12)

win.setBackground("green3")

#Draw the interface widget by creating three button

door1 = Button(win, Point(-7.5, -3), 5, 6, "Door 1")

door2 = Button(win, Point(0, -3), 5, 6, "Door 2")

door3 = Button(win, Point(7.5, -3), 5, 6, "Door 3")

#Assign the text to the interface

direction = Text(Point(0, 10), "Pick a Door")

#Call the method draw

direction.draw(win)

#Get the random number

x = random() * 3

#Assign the values to false

point1 = point2 = point3 = False

#check the condition

if 0 <= x <1:

#Assign point1 to True

point1 = True

#Chcek the condition

elif 1 <= x < 2:

#Assign the point2 to True

point2 = True

#Otherwise

else:

#Assign the point3 to True

point3 = True

#Activate all the three doors

door1.activate()

door2.activate()

door3.activate()

#Get the action mouse click

click = win.getMouse()

#Check the condition using "while" loop

while door1.clicked(click) or door2.clicked(click) or door3.clicked(click):

#If door1 is clicked

if door1.clicked(click):

#Assign point1 to true

if point1 == True:

#Update the interface

door1.update(win,"Victory!")

else:

#If door1 is clicked

if door2.clicked(click):

#Update the interface

door2.update(win,"Correct Door.")

#Get the action mouse click

click = win.getMouse()

else:

#Update the interface

door3.update(win,"Correct door.")

#Get the action mouse click

click = win.getMouse()

#If door2 is clicked

elif door2.clicked(click):

#Assign point2 to true

if point2 == True:

#Update the interface

door2.update(win,"Victory!")

else:

#If door2 is clicked

if door3.clicked(click):

#Update the interface

door3.update(win,"Correct Door.")

#Get the action mouse click

click = win.getMouse()

else:

#Update the interface

door1.update(win,"Correct door.")

#Get the action mouse click

click = win.getMouse()

else:

#Assign point3 to true

if point3 == True:

#Update the interface

door3.update(win,"Victory!")

else:

#If door2 is clicked

if door2.clicked(click):

#Update the interface

door2.update(win,"Correct Door.")

#Get the action mouse click

click = win.getMouse()

else:

#Update the interface

door1.update(win,"Correct door.")

#Get the action mouse click

click = win.getMouse()

#Call the getMouse()

win.getMouse()

#Call the main function

main()
