Question

Design and implement a Python program which will allow two players to play the game of Tic-Tac-Toe in a 4x4 grid!

X | O | X | O

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

O | O | X | O

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

X | X | O | X

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

X | X | O | X

The rules for this game is the same as the classic, 3x3, game –

• Each cell can hold one of the following three strings: "X", "O", or " " (Blank)
• 4 X’s (or 4 O’s) in a row or column; or across a diagonal wins

Requirements

Part A: 20 Points – At a minimum, implement the following three functions –

• create_board() which will allow a user to build an “empty” board (so that we can start a game
• display_board() which will show the current board
• check_winner() that determine if there is a winner for the game

• If "X" appears in a winning Tic-Tac-Toe pattern, the function should return
• the string "X"
• If "O" appears in a winning Tic-Tac-Toe pattern, the function should return the string "O"
• If no winning pattern exists, the function should return the string " "
• Break your logic into functions, don’t implement the entire game in a single function, like “main”

Part B: 20 Points – Implement logic so that two players can play the game for as many times as they wish to. In addition -

• Ask users for their names
• Display the numbers of wins vs. losses for each player once they are done with playing

Part C: 5 Points – Enhance your project to include an option for a “player” to play against a “computer” instead

Assumptions

• You may include additional functions, however, you MUST implement the specified functions – they are required.

Given data,

Python solution with output screenshot:

Code :

def create_board():
    board = [' '] * 16
    return board

def display_board(board):
    for i in range(16):
        if((i+1)%4==0):
            print(board[i])
            if(i<15):
                print("--------------")
        else:
            print(board[i], end=" | ")
