Introduction to Computer Science and Programming

Spring 2005

Lab Assignment 6

The Mastermind Game

 

Step 1

 

Study the following web page:

http://www.coquitlamcollege.com/adawson/MasterMindRules.htm

 

Step 2

 

Play a sample game:

http://www.bfoit.org/Intro_to_Programming/mastermind.html

 

In your own version of the game, you will use the six numbers: 1,2,3,4,5,6 instead of six colours, and the combination of numbers to be guessed must not contain duplicates (you may assume that the user of the game will not enter duplicate numbers in their guesses). You must use a Python list to store the 4 number combination, and a Python list to store the score.  The user gets a maximum of ten guesses to get the correct combination.

 

Example:

 

If the combination is:

 

1234  

 

And the first guess is

 

2345

 

The score is 0,3  (Meaning 0 numbers in the correct position, but 3 correct numbers).

 

 

An example game:

 

Hidden correct combination: 2461

(2461)

 Guess     Score

 1234       0  3

 4321       1  2

 3421       2  1

 2431       3  0

 2451       3  0

 2461       4  0    You win in 6 guesses!

 

 

For Bonus points, enforce unique number entry (no duplicates) and generate a random 4 number sequence to be guessed at the start of each game. At the end of the game, ask if the user wishes to play again, and repeat the game on request.

 

Step 3

 

Study the algorithm below.

 

Algorithm:

 

1.  Create a list of any 4 unique numbers in the range 1 - 6.

2.  Ask the user to input their guess: 4 unique numbers in the range 1 - 6.

3.  Check each inputted number against the hidden combination:

            If the guessed number is in the correct position add 1 to a score counter

            If the guessed number is one of the correct numbers but is in an incorrect

            position add 1 to a second score counter.

4.  After each guess add 1 to a guess counter

5.  Display the guess number and score counters

6.  If first score counter has a value of 4, player wins. Game over. Go to step 9.

7.  If the guess counter has a value of 10, player loses. Game over. Go to step 9.

8.  If player has not won or lost,

           Set score counters back to zero.

           Go back to step 2.

9. Output win or lose status and end.

 

Create your own pseudocode from the given algorithm.

 

Step 4

 

Using your pseudocode as a guide, implement your program in the Python language. Use the IDLE GUI to edit and run your program:

http://www.coquitlamcollege.com/adawson/Python_Editor_IDLE.htm

 

Your program should start with a comment block that contains the following information:

 

#  File:       lab6.py

#  Purpose:    The Mastermind Game

#  Programmer: [your name]   

#  Partner:    [your partner's name]

#  Course:     CSCI120A

#  Date:       Monday 21st February 2005

 

Step 5

 

Test your program by supplying your own test data. You should test your program with at least 3 sets of test data. Show your test data and results in comments at the top of your program.

 

Step 6

 

At the end of the class, save your program file (lab6.py) to your folder on the network in:

 

CSCI120A\Week08\Lab06

 

 

Program points will be based on the following marking scheme:

Bonus Points

5

For Bonus points, enforce unique number entry (no duplicates) and generate a random 4 number sequence to be guessed at the start of each game. At the end of the game, ask if the user wishes to play again, and repeat the game on request.
