Assignment 3: due 8am on Mon, Oct 29, 2018

Summary of Instructions

Note Read the instructions carefully and follow them exactly

Assignment Weight 6% of your course grade

Due Date and time 8am on Monday, Oct 29, 2018

Important

As outlined in the syllabus, late submissions will not be accepted.

Any files with syntax errors will automatically be excluded from grading. Be sure to test

your code before you submit it

For all functions, both in Part 1 and 2, make sure you’ve written good docstrings that

include type contract, function description and the preconditions if any.

This is an individual assignment. Please review the Plagiarism and Academic Integrity policy presented in the first

class, i.e. read in detail pages 15 ? 18 of course outline (ITI1120-course-outline-syllabus-Fall2018.pdf). You can

find that file on Brightspace under Course Info. While at it, also review Course Policies on pages 13 and 14.

NEW: From this assignment onwards you must follow the following procedure if you use any code that you did not

write yourself i.e. that you copied from somewhere (be it from internet, or a friend ...). It is not enough that you put

such references inside of the comments of your program. If you use somebody else’s code, you must create a file called

references.txt and in that file provide a list of all the reference of the material that you used. In such a case you may

have points deducted. The number of points deducted will depend on the level of help the reference provided (from 0

to 100%). But with proper referencing there is no danger of finding yourself in a plagiarizing position.

The goal of this assignment is to learn and practice the concepts covered thus far: function design, lists and loops.

You can make multiple submissions, but only the last submission before the deadline will be graded. For this assignment,

you do not need to submit a3_xxxxxx.txt as proof that you tested your function. By now we trust that you learnt and

understand the need and importance for testing your functions and code in general.

You can make multiple submissions, but only the last submission before the deadline will be graded. What needs to

be submitted is explained next.

The assignment has two parts. Each part explains what needs to be submitted. Put all those required documents into

a folder called a3_xxxxxx where you changed xxxxxx to your student number, zip that folder and submit it as explained

in Lab 1. In particular, the folder should have the following files:

In part 1 you will implement 3 small programs. In part 2, you will implement a card game. Put all the below four

required documents into a folder called a3_xxxxxx.zip that folder and submit it as explained in lab 1. (In particular,

the folder (and thus your submission) should have the following files:

Part 1: a3_Q1_xxxxxx.py, a3_Q2_xxxxxx.py, a3_Q3_xxxxxx.py

Part 2: a3_GAME_xxxxxx.py

Both of your programs must run without syntax errors. In particular, when grading your assignment, TAs will first

open your file, say a3_GAME_xxxxxx.py with IDLE and press Run Module. If pressing Run Module causes any syntax

error, the grade for Part 2 becomes zero. The same applies to Part 1.

Furthermore, for each of the functions (in Part 1 and Part 2), I have provided one or more tests to test your functions

with. To obtain a partial mark your function may not necessarily give the correct answer on these tests. But if your

function gives any kind of python error when run on the tests provided below, that question will be marked with zero

points. Test/example runs for each function in part 2 are given inside of its docstrings in the provided starter file

a3_game_xxxxxx.py.

To determine your grade, your functions will be tested both with examples provided in Part 1 and a3_game_xxxxxx.py

and with some other examples. Thus you too should test your functions with more example than what I provided in Part

1 and a3_game_xxxxxx.py.

1

Keywords: break and continue are not allowed.

Global variables are not allowed. If you do not know what that means, for now, interpret this to mean that inside

of your functions you can only use variables that are created in that function. For example, this is not allowed, since

variable x is not a parameter of function a_times(a) nor is it a variable created in function a_times(a). It is a global

variable created outside of all functions.

def a_times(a):

result=x*a

return result

x=float(input("Give me a number: "))

print(a_times(10))

1 Part 1 20 points

For this part of the assignment, you are required to write three short programs. For this part you need to submit 3 files:

a3_Q1_xxxxxx.py, a3_Q2_xxxxxx.py, and a3_Q3_xxxxxx.py.

1.1 Question 1: (5 points)

Implement a Python function called count_pos that takes a list of numbers as an input parameter and returns the number

of elements of that list that are positive (i.e. > 0). Then, in the main, your program should ask the user to input the

list, then it should call count_pos function with that list, and print the result. In this question you may assume that the

user will follow your instructions and enter a sequence of numbers separated by spaces. You can use str method .strip

and .split to handle the user input. Here is a way to ask a user for a list:

raw_input = input("Please input a list of numbers separated by space: ").strip().split() But now raw_input

is a list of strings that look like numbers so you need to create a new list that is a list of equivalent numbers.

Three examples of program runs:

Please input a list of numbers separated by space: 2 3.5 -1 -100

There are 2 positive numbers in your list.

Please input a list of numbers separated by space: 1 0 22 0 1

There are 3 positive numbers in your list.

Please input a list of numbers separated by space:

There are 0 positive numbers in your list.

Function call example:

>>> count_pos( [1, 0, 22.2, 0, 1.0, -10.5] )

3

1.2 Question 2: (5 points)

Implement a Python function called two_length_run that takes a list of numbers as input parameter and returns True

if the given list has at least one run (of length at least two), and False otherwise. Make sure the function is efficient (i.e.

it stops as soon as the answer is known). Then, in the main, your program should ask the user to input the list, then it

should call two_length_run function, and print the result. You can obtain a list of numbers from the user as explained

in Question 1.

Four examples of program runs:

Please input a list of numbers separated by space: 1 4 3 3 4

True

Please input a list of numbers separated by space: 1 2 3 3 3 4.5 6 5

True

Please input a list of numbers separated by space: 1.0 2 3.7 4 3 2

False

Please input a list of numbers separated by space: 7.7

False

2

Function call example:

>>> two_length_run( [2.7, 1.0, 1.0, 0.5, 3.0, 1.0] )

True

1.3 Question 3: (10 points)

As mentioned, a run is a sequence of consecutive repeated values. Implement a Python function called longest_run

that takes a list of numbers and returns the length of the longest run. For example in the sequence:

2, 7, 4, 4, 2, 5, 2, 5, 10, 12, 5, 5, 5, 5, 6, 20, 1 the longest run has length 4. Then, in the main, your

program should ask the user to input the list, then it should call longest_run function, and print the result. You can

obtain a list of numbers from the user as explained in Question 1.

Five examples of program runs:

Please input a list of numbers separated by space: 1 1 2 3.0 3 3 3 3 6 5

5

Please input a list of numbers separated by space: 6 6 7 1 1 1 1 4.5 1

4

Please input a list of numbers separated by space: 6 2.4 4 8 6

1

Please input a list of numbers separated by space: 3

1

Please input a list of numbers separated by space:

0

Function call example:

longest_run([6, 6, 7, 1.0, 1.0, 1.0, 1, 4.5, 1])

2 Part 2: Single Player Rummy Game with Dice and strange deck

(80 points)

To clarify Part 2 specifications, I have provided sample tests for each required function inside of its docstrings in

a3_game_xxxxxx.py. Furthermore, you can find example run of the whole game below and its associated video at

the link below. The behaviour implied by the sample tests/runs and the video should be considered as required specifications

in addition to what is explained in this document. Finally, you can also find one extra example run of the

beginninng of the game that the end of the assgnment.

Here is the link to the video: https://youtu.be/Zwl2qTyPnHo

Description:

A card in a standard deck has a suit (in particular, one of four suits: r, ?, q, ?) and a rank (one of 13 ranks: A, 2, 3, ...,

10, J, Q, K). Taking every pair of a suit and a rank gives rise to a standard deck of (4x13=) 52 cards. Imagine you have

access to only an old fashion terminal that cannot display fancy characters like: r, ?, q, ? but yet you would like to make

a card game. You would first need to decide how to represent a card. One way to do that would be to represent a card by

a 3 digit integer where the first digit (1 to 4) represents a suit and the two last digits (1 to 13) represent ranks. Let’s call

such a deck, a strange deck.

For part 2 of the assignment, you will need to make a (heavily) modified version of Rummy card game with this

strange deck. In Rummy, the main goal is to build melds which consists of sets, two, three or four of a kind of the same

rank; or progression, three or more cards in a sequence of consecutive ranks, of the same suit. So the set r10, q10, ?10

forms three of a kind. And the set/sequence 7q, 8q, 9q, 10q, 11q forms a progression. In our strange deck, 210, 110, 310

would form three of a kind (since the first digit is a suit, so the ranks are 10, 10, 10) and the set 309, 307, 311, 308, 310 is

a progression (since they all have a suit 3 and 07, 08, 09, 10, 11 is sequence of consecutive integers). Note that 201, 302,

303 is not a progression. Although 01, 02, 03 is a sequence of consecutive integers, the three cards do not have the same

suit (some have suit 2 and some 3) so this is not a progression.

3

So the game that you will develop needs to go as follows: (The goal of the player is to get rid of all of her cards in as

few rounds of the game as possible)

Step 0: The strange deck is created and shuffled. (In order to test your game more

quickly you can reduce the numer of ranks to less than 13 and more than 3). In your

implementation the created deck needs to be a list of integers

representing a strange deck. Top of the deck is considered the last card in the list.

Step 1: The player is dealt 7 cards from the top of the strange deck.

Step 2: The following steps are repeated until the player runs out of

the cards:

Step 3: The player rolls a dice

If the player gets a 1:

The player can discard any one card she likes. After that, the current round

is over and the game goes back to Step 2.

If instead the player gets num=2,3,4,5 or 6:

The player if first delt, from the top of the deck,

num or len(deck) cards, whichever is smaller.

The player then keeps on discarding melds from her hand

until she has no more melds. You program has to check

that the set of cards that the player chooses indeed forms a

valid meld before discarding them from the player's hand.

Once she decides she is out of melds, the round is over

and the game goes back to Step 2.

(Note that once the deck is empty and the player has no more melds,

no melds can ever be created again. Thus the player has to wait for 1 on the

dice. In order to avoid that unpleasantry your game should roll 1

i.e. set num to 1, in each round that starts with empty deck.)

Finally, once the player is out of cards, the total number of rounds

is reported.

As usual, whenever you ask the player for some input you should make sure they give you the required kind of input.

You may assume that the player will follow instructions and give you a correct type of date but not the correct values.

For example, if you are asking for an integer between 3 and 99, you may assume that the player will give you an integer

but not that she will give you an integer in the correct range. Thus you should keep on repeating the question until you

get a valid answer. Similarly if you ask the player for a meld, you may assume that the player will give you a set of 3

digit integers, but you will need to test if these cards are indeed in the players hand and that they form a meld.

As in the previous assignment, I provided you with the starter code in the file called, a3_game_xxxxxx.py. Start by

replacing xxxxxx in the file name with your student number. Then open the file. Your solution (code) for this part must

go into that file in the clearly indicated spaces only. You are not allowed to delete or comment-out or change any parts

of the provided code except for the keywords pass.

In a3_game_xxxxxx.py, there are many functions with code missing. You must complete and use all of those functions.

Your function should behave as explained in the function description and the example runs. All rea given in the

docstrings. You also need to complete the main.
