Question

PYTHON 3.4

You should program a version of the memory game.  The game is usually played with cards. If you do not know what it is, google it or see and play a bit here.

Only your game will not use graphics libraries to display the board, but instead it will print the board with the tools i.e. printing on Python console.

Your game should use a (one dimensional) list as the board. The size of the board should be an even integer, size, between 2 and 52. This number should be obtained from the player. The board should be filled with the first size/2 capital letters of english alphabet such that each
letter appears exactly twice in the list. And the order of these letters in the list should be random. I provided you witha function called create_board, that does this for you.

You will see that in the file i attached, it has a function called play_game(board). That is where you should put your game paying code
(notice the #YOUR CODE GOES HERE comment inside of that function) The function play_game takes the board as input parameter (the board created by the function create_board mentioned above). Once the player completes the game, you should also print the number of guesses it took to solve it and how far it is from the optimal (although impossible without luck) size/2 guesses.

Outside of that function you will obtain the desired size of the board from the player (in the space indicated by #YOUR CODE GOES HERE TOO).

More info about the game.

When your program prints the board, the locations for which paring is not discovered yet should display * and the locations for which the paring is discovered should display the letter that is on that location. In addition under the board each location should be labeled from 1 to size to help the user identify which locations they want opened next.

You may assume that the player will follow your instructions and will input integers (rather than strings say), but your program should test if the player entered integers in the required range and prompt her to repeat the entry until correct input is obtained. You should also fully test your program -- for example, what does your program do if the player does something silly, like entered two locations that are already discovered, etc .. Here is what a run of your program should look like.

Study the below example carefully to understand what your program should do. Among other things, you will see that your program will need to ``clear screen'' (I explain why is this needed more at the end of this file). It is ok to implement that by, for example, simply printing 30 or so new lines.

You will also see that you will need to pause the execution of the program so that the player can look at the newly opened two elements. Once the player has observed the two new elements that she should presse enter and the program will continue (you can assume here that she follows instructions). To have your program pause and wait for the player to press enter use the provided function called wait_for_player.

Also, think of the design of your program. For example, your program should have a function that displays the current board (I provided
that), but it should also have a function that displays the board with two new positions revealed (did not provide that). These functions would be called from your game playing function.

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. You will be graded on these aspects of your program too.

Here is finally what a run of your program should look like:

Your program:

How many cards do you want to play with?

Enter an even number between 2 and 52:

Player: 5

Your program:

How many cards do you want to play with?

Enter an even number between 2 and 52:

Player: 6

Your program:

* * * * * *
1 2 3 4 5 6

Enter two distinct locations on the board that you want revealed.

i.e two integers in the range [1, 6]

Player: 1

2

Your program:

C B * * * *

1 2 3 4 5 6

Press enter to continue

Player: presses enter

Your program: clears the screen (so that the above board is not visible) and prints

* * * * * *
1 2 3 4 5 6

Enter two distinct locations on the board that you want revealed.

i.e two integers in the range [1, 6]

Player: 3

C B A C A B

1 2 3 4 5 6

Press enter to continue

Player: presses enter

Your program prints

C B A C A B

1 2 3 4 5 6

Congratulations! You completed the game with 7 guesses.

That is 4 more than the best possible.

an extra note:

Here is a brief clarification about why you need to be able to "clear" the screen and pause the game:

For example, let's say your program just printed the current board.

B * * B * *

1 2 3 4 5 6

Then it asks the player to enter two new locations, and player enters 2 and 3

Then your program will print:

B A C B * *

1 2 3 4 5 6

It is here that you need to pause the program. After the player observed the two new locations, the next thing that needs to be done
is to clear the screen (meaning the above thing should not be visible anymore) and print the board again. Which would print

B * * B * *

1 2 3 4 5 6

If you do not pause where I stated above, the computer will do the above so fast that the player will only see

B * * B * *

1 2 3 4 5 6

Then she will be asked to enter two new locations, but after she enters them she will only get to see this again (since the board with two new locatins is already gone from the screen)

B * * B * *

1 2 3 4 5 6

As for clearing the screen, you can do that by e.g. calling print() about 30 or more times
