Objectives:

Practice on List

More practice on writing loops in python.

More practice on writing and calling functions that you have written. Practice testing your code.

To appreciate the benefits of modular development.

Program Description:

For this program, you will be writing a simulation for the game, Tic-Tac-Toe. Two people play Tic Tac Toe with paper and pencil. One player is X and the other player is O. Players take turns placing their X or O. If a player gets three of their marks on the board in a row, column or one of the two diagonals, they win. When the board fills up with neither player winning, the game ends in a draw.

This program has two parts:

    1. Two Players

    2. Play with Computer
Part One: Two Players

Take user input (for two players)

Store user inputs into a 3x3 Tic-Tac-Toe board

Check for validity of inputs (no overriding, proper cell value, etc.) Check for a win every turn

Print the board every turn

Part Two: With Computer

Randomly pick a player (you or computer) Take input (for one players)

Computer or you will generate the next

Store user inputs into a 3x3 Tic-Tac-Toe board

Check for validity of inputs (no overriding, proper cell value, etc.) Check for a win every turn

Print the board every turn

Getting Player Input:

Each player will input a number (1-9) which corresponds to the following cells.


1    2    3

4    5    6

7    8    9


Location 0 in list corresponds with number 1

Players’ input will be stored in a list.

Players will take turns.

Checking For a Win:

A player wins if there is a sequence of 3 of the same letter in the same row, column, or diagonal.

Printing Output:

You should use for loops to output a 3x3 board.


General Notes:

You should implement your functions in a file, tictactoeFuncs.py Checking for a win requires multiple operations.
Functions:

    1. Welcome

        a. Welcomes user to the game and explain the game rules.

        b. You will provide your own Welcome information

        c. Ask user to decide if playing with computer (pass 1) or another player (pass 2)

        d. No parameter to pass

        e. Return 1 if play with computer and 2 if plays with another player

    2. createBoard

        a. You will use a list to store the data

        b. List has 9 items starting from index 0 to 9 which holds the values (X or O)

        c. This function has no parameter to pass and it return a list

        d. Your game board at first should look like the following:

1|2|3

---------------

4|5|6

---------------

7|8|9

    3. printBoard

        a. The printBoard function will print the game. Remember that the board is represented as a list of nine strings, where the string at index 0 is the mark on space 1 on the Tic Tac Toe board, and so on.

        b. Passing a list as the board to the function.

        c. The first call to the print will show an empty board game:

|    |

---------------

|    |

---------------

|    |

    4. pickLetter

        a. This function ask user to pick ‘X’ or ‘O’

        b. No parameter to pass

        c. This will return the letter of player’s choice

        d. If user enters the wrong letter you need to ask user to reenter the letter

        e. This function return letter

    5. getInput

        a. This function takes the letter and board as parameters

        b. Ask user to enter the letter of his/her choice in the one of the locations (1-9) on the board

            i. Where do you like to place your letter (pick in range of 1-9)

            ii. If user repeat the location or pass value outside range (1-9) for placing the letter:

                1. Send a message:

a.  Invalid move! Location is already taken. Please try again.

        c. This function will return the board after entering the letter

    6. checkRows

        a. takes the board as parameter

        b. returns True and the letter if a row is filled with the same Letter

    7. checkCols

        a. takes the board as parameter

        b. returns True and the letter if a column is filled with the same Letter

    8. checkDiags

        a. takes the board as parameter

        b. returns True and the letter if any of diagonals are filled with the same Letter

    9. boardFull

        a. takes the board as parameter

        b. returns True if the board is full

    10. checkWin

        a. takes the board

        b. if any of checking (rows, columns, diagonals ) returns True

            i. announce the winner

        c. if board is filled and no winner announce draw!

    11. turnCount

Use this function to show, which turns the game is. Example:
It's Player 2's (O' )turn!

        a. takes count of turns

        b. increment counter

        c. return counter

Resources:

You can download the following files from PolyLearn:

testFunctions.py, at least 2 test cases for each function tictactoeFuncs.py

incol (test file for two player) inrow (test file for two player) india (test file for two player)

For testing your program with these files:

python3 tictactoe.py < incol

python3 tictactoe.py < inrow

python3 tictactoe.py < india



Note:

You can add any extra functions you need. You have freedom on how you format your messages. Make sure to follow the steps. The sample screenshot is given.

USE EXACTLY THE SAME FUNCTIONS’ NAME.
