Read the instructions below carefully. The instructions must be followed.

Need answer for ITI1100 assignment.

Read the instructions below carefully. The instructions must be

followed. This assignment is worth 5% of your grade. The

assignment is due on Monday 31st of October at 8AM. No late

assignments will be accepted.

The goal of this assignment is to learn and practice (via

programming ) the concepts that we have learned so far. This

includes lists and range function. You will also learn how to solve a

bigger problem (making a game) by breaking it into smaller parts.

This assignment has two parts. 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:

a3_Q1_xxxxxx.py,

a3_Q2_xxxxxx.py

a3_Q3_xxxxxx.py

a3_GAME_xxxxxx.py

For each function that you design for this assignment you have to

include docstrings that specify:

- type contract

- description about what the function does (while mentioning

parameter names)

- preconditions, if any.

For this assignment, unlike previous two, you do not need to

submit a text file as evidence that you tested your functions. But

as always, you are strongly encourage to test all your functions in

Python shell as you have learnt in the previous assignments.

As always, your programs must run without syntax errors.

PART 1 (20 points)

*****************************************************************************************************************

=====================

Question 1: (5 points)

=====================

Implement a Python function called count_pos that takes a list of

numbers as input (parameter) and returns the number of elements

of that list that are positive (> 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. You may assume that

the user will always enter at least two elements, but your function

count_pos should work for all lists of numbers including those of

length 0 and 1.

Examples of program runs:

Example 1:

Please input a list of numbers separated by

commas: 1,2,0,3,0,4

There are 4 positive numbers in your list.

Example 2:

Please input a list of numbers separated by

commas: 1,-2,9

There are 2 positive numbers in your list.

Here is a way to ask a user for a list:

s = input("Please input a list of numbers

separated by commas: ")

l = list(eval(s))

If a user enters at least two numbers separated by commas,

variable l will refer to that list.

=====================

Question 2: (5 points)

=====================

A run is a sequence of consecutive repeated values. Implement a

Python function called two_length_run that takes a list of numbers

as input and returns True if the given list has is 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 may

assume that the user will always enter at least two elements, but

your function two_length_run should work for all lists of numbers

including those of length 0 and 1.

Examples of program runs:

Example 1:

Please input a list of numbers separated by

commas: 1,4,3,3,4

True

Example 2:

Please input a list of numbers separated by

commas: 1,2,3,3,3,4,6,5

True

Example 3:

Please input a list of numbers separated by

commas: 1,2,3,4,3,2

False

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 may assume that the user will

always enter at least two elements, but your function longest_run

should work for all lists of numbers of length at least 1.

Examples of runs:

Example 1:

Please input a list of numbers separated by

commas: 1,1,2,3,3,3,3,3,6,5

5

Example 2:

Please input a list of numbers separated by

commas: 6,6,7,1,1,1,1,4, 1

4

Example 3:

Please input a list of numbers separated by

commas: 6,2,4,8,6

PART 2 (80 points)

*****************************************************************************************************************

For this part, you will program a card game described here:

http://www.classicgamesandpuzzles.com/Old-Maid.html

You will implement the two player version. One player will be the

computer (i.e. your program) and the other a user of your

program. In what follows, let's refer to the computer player as

Robot and user player as Human. You may assume that Robot will

always deal the cards.

As part of this assignment I provided the file called

a3_GAME_xxxxxx.py. Replace xxxxxx in the file name with your

student number. You should open that file and run it to see what it

does already. All of your code has to go inside of that file. The file

already has some functions that are fully coded for you and other

functions for which only docstrings and partial or no code are

provided. Designing your program by decomposing it into smaller

subproblems (to be implemented as functions) makes programming

easer, less prone to errors and makes your code more readable.

No part of the given code can be changed. Your code must go into

clearly indicated places. No code can be added to the main. You

can design some extra functions of your own if you like.

Functions make_deck, wait_for_player and shuffle_deck are

already fully coded for you.

You need to develop the remaining functions: deal_cards,

remove_pairs, print_deck, get_valid_input, and play_game.

The functions must meet the requirements as specified in their

docstrings (and as implied by the example program runs below and

in the video).

The main bulk of your code (the game playing part) will go into the

function called play_game. That function should use/call the

other functions that you are required to develop (i.e. deal_cards,

remove_pairs, print_deck, and get_valid_input).

When developing function get_valid_input you may assume that

Human will enter integer when asked for an integer,

but you may not assume that it will be in the correct range.

The function get_valid_input gets the input from Human about

which face-down card of Robot it wants. When it is Robot's turn to

play you must implement it such that Robot takes a random card

from Human. Also recall that what Human calls 3rd card, for

example, is in position/index 2 in Robot's deck (as it is represented

by a list).

Study the example of the program run below carefully to

understand how your program should behave. The behaviour of the

program that you see in the run is required — all aspects of it.

Also watch the video I made to get even better idea of how your

program must behave. The video can be found here:

https://youtu.be/TSj40i6XbaU

Some suggestions:

1. Study the provided code and understand what it does and how it

should be used.

2. Spend some time thinking about various parts of the game that

need to be implemented. For example, it needs to be able to

display Human's deck to Human, it needs to be able to ask Human

for what card she wants, it needs to be able to remove pairs from

either Human or Robot's deck ... etc.

The provided functions do quite of bit of that job for you. In the

next assignment, Assignment 4, you will need to be breaking the

problem into small subproblems (to be implemented as functions)

by yourself.

3. When you are coding individual functions recall that you can

test each function in the shell without finishing the remaining

functions. For example, when implementing function

remove_pairs you can test it in the shell by typing something like:

>>> remove_pairs(['10♣', '2♣', '5♢', '6♣', '9♣',

'A♢', '10♢'])

The shell should display (with cards not

necessarily in this order):

['2♣', '5♢', '6♣', '9♣', 'A♢']

Thus you can code and test your functions one by one (without

completing the other parts)

4. The game alternates between Robot and Human. Think about

how you can represent whose turn it is to play, in your program.

One way is to have a variable that you set to zero when it is

Robot's turn and to one when it is Human's turn. You also need to

figure out what to test to see if the game is over.
