Assignment 4

Lists and Strings

Submit a single zip file called assignment4.zip. This zip file should contain all the files you

create as part of this assignment. Each question will specify the name of the file you should

create. Make sure you name your files precisely.

This assignment has 50 marks.

See the marking scheme that is posted on the assignment page for details.

Problem 1 (File Analysis)

For this problem, create a file named a4q1.py. Within this file, write a program that does the

following:

1. Ask a user for a filename

2. Open the specified file

3. Print out the following information:

a. The total number of words in the file

b. A list of the longest words in the file (the greatest number of characters)

c. A list of the shortest words in the file (the least number of characters)

d. The average word length of all words in the file

4. Close the specified file

For the purposes of this assignment, you can assume that a single word is any text contained

between spaces. This may include punctuation – for example, the text “didn’t” would be

considered a single word, as would the text “cold,”. Your lists of longest/shortest words should

not contain any duplicates (remember, ‘A’ and ‘a’ are not considered duplicates).

On the assignment page, there are 5 test files that you can use (fileanalysisX.txt) along with a

summary of the expected output (fileanalysisX-expectedoutput.txt). You can use these files to

verify your results. Note: you do not need to write files that match the expected output files

– they are just copies of the correct printed output (i.e., your printed information should

look the same). Remember to break the problem down and approach it in a similar fashion to

the previous assignment.

Problem 2 (Mastermind)

For this question you will create a version of the popular game mastermind! Go here to play an

online version of the game: Mastermind online (Note, the game you make will look and behave

differently). You should save your game program in a file called a4q2.py.

The rules for your game are as follows:

You randomly generate a password of 5 digits between [0-9]. (e.g.: [3,1,4,4,2])

The user then has 10 turns to guess the password.

Each turn the user makes one guess, and your program reports how many digits were

correct.

o Note: a correct guess is the right number in the right location.

o Note: be careful with datatypes!

If the user guesses all five digits correctly, the game ends with a win message.

If the user runs out of turns, the game ends with a lose message.

You may assume that the user correctly enters 5 integers, however you must allow them to

enter all 5 into a single prompt (separated by spaces). (Tip: the string.split() method might be

useful here.)

Example Game Output (text entered by the user is highlighted):

I've set my password, enter 5 digits in the range [0-9] separated by spaces (e.g. 1 3 2 4 4):

10 guesses remaining > 1 2 3 4 5

1 of 5 correct

9 guesses remaining > 2 3 4 5 1

0 of 5 correct

8 guesses remaining > 2 2 3 4 5

1 of 5 correct

7 guesses remaining > 3 3 3 4 5

1 of 5 correct

6 guesses remaining > 4 4 4 4 5

2 of 5 correct

5 guesses remaining > 5 5 4 5 5

1 of 5 correct

4 guesses remaining > 3 2 1 4 5

2 of 5 correct

3 guesses remaining > 1 1 1 4 5

3 of 5 correct

2 guesses remaining > 2 1 1 4 5

3 of 5 correct

1 guesses remaining > 3 1 3 4 5

2 of 5 correct

You'll never get my treasure because the password was ['4', '1', '1', '2', '5']
