assignment3. the card game : war

due date: today!!!

Pedagogical Goal: Refresher of Python and hands-on experience with algorithm coding, input validation, exceptions, file reading, Queues, and data structures with encapsulation.

Task 1 : Reading and Validating cards

You are given a text file of 52 shuffled cards, each card is in a line coded on two characters as described above. You need to prompt the user for the name of the file, open the file and read it. Make sure the file exists and make sure the cards in the file are correctly formatted as described above. If the cards are in lower case, it is not an error as you can simply transform them in upper case. You can assume the cards are shuffled but don't assume they are formatted as specified or that there are exactly 52, or even that they are not repeated. Make sure all the standard 52 cards are there in the shuffled deck. You are not asked to correct the cards, but your program must raise and catch an exception if card validation does not go through. The program should then display an appropriate error message and terminate the program in case there is an issue with the cards.

You are given a python program shuffleCards.py that generates the file shuffledDeck.txt as we described above with 52 lines constituting the shuffled deck. However, while this program generates a correct input to your program don't assume the input file is always correct. The assessment of your assignment may be made with a file that is incorrect.

Task 2: Distributing cards

Now that you have read the 52 cards from the file and you know you shuffled deck is complete and correct, distribute the cards to both players: the user and the computer. You may call them player1 and player2. You should give one card to each player repeatedly until all cards are distributed. You should start randomly with either player.

The players keep their cards in such a way that the first card served is the first that will be played. In other words, the containers of these cards should receive the cards on one end and use them from the other end. Use the circular queue we saw and implemented in class to represent the player's hand. The capacity should be set to 52 since you will never have more than 52 cards. The Circular Queue class should be inside assignment3 file that you submit.

Task 3: Asking user for data

Ask the user whether they would like to play a war with one, two, or three cards face-down. validate the input from the user and don't proceed until a valid input is given.

Example of a War with 3 cards down

Task 4: Comparing cards

You need a way to compare two cards. Write a function that given two correct cards returns 0 if the cards are of equal rank; 1 if the first card is of higher rank; and -1 if the second card is of higher rank. The ranks are explained above. Also, remember that the rank is the first character of the card and the cards are strings of two characters.

Task 5: class OnTable

We need to represent the cards on the table, the cards that are currently placed on the table by both players either face-up or face-down. Create an encapsulated class OnTable with the behaviour described below. We will use two simple lists: one list for the cards and one list to indicate whether they are face-up or face-down. The attributes of the class are: __cards which is a list that will contain the cards, and __faceUp with will have booleans to indicate if the __cards list in the same position in __cards is face-up or face-down. Cards put on the table by player 1 will be added on the left of self._cards. The cards put on the table by player 2 will be added on the right of self._cards. The interface of this class should include place(player, card, hidden), where player is either 1 or 2 for player 1 or player 2, card is the card being placed on the table, and hidden is False when the card is face-up and True when the card is face-down. This method should update the attributes of the class appropriately. The interface should also have the method cleanTable(). This method shuffles and then return a list of all cards on the table as stored in the attribute __cards and resets __cards and __faceUp. All cards returned this way are visible. Finally, also write the method __str__() that should allow the conversion of the cards on the table into a string to be displayed. We would like to display the cards as a list. However, cards that are face-down should be displayed as "XX". Moreover, player1 and player 2 cards should be separated by a vertical line.Please see sample output.

Task 6: The Game

Given the following algorithm and based on the previous tasks, implement the card game War. Obviously, there are details in the algorithm specific to the implementation in Python that are missing and it is up to you as an exercise to do the conversion from this pseudo-code to Python.

There are other practical details to add to the algorithm. At the end of the game, we need to display who was the winner (player1, the user, or player2 the computer). As indicated in the algorithm, on line 45 and 46, after each round of the game, 60 dashes are displayed and the program will wait for the user to press enter before displaying the next round.

ple

please be follow the structures and please finish do by shortly

if you can't finish, partially finish the structures are okay.
