Python Tic-Tac-Toe with Minimax Algorithm

This Python script implements a simple Tic-Tac-Toe game where a human player can play against an AI that uses the minimax algorithm. The game is played on a 3x3 board.

Features

• Human vs AI Gameplay: Play against a computer AI that evaluates moves using the minimax algorithm.
• Command Line Interface: Simple text-based interface to play the game in the command line.
• Input Validation: Ensures that only valid integers are accepted as input.

Requirements

This script requires Python 3.x. No additional libraries are necessary.

Code Structure

• read_int(prompt): Function to read and validate integer inputs.
• check_winner(board): Function to check the current state of the board for a winner or a draw.
• minimax(board, depth, is_maximizing, player): The minimax function to calculate the best move for the AI.
• TicTacToe Class:
  • Methods to manage game state, validate moves, make moves, and display the board.

Game Flow

1. The game is initiated and the board is displayed.
2. Player 1 (human) is prompted to enter a move.
3. Player 2 (AI) calculates and makes the next move.
4. Steps 2 and 3 repeat until the game ends with a win or a draw, at which point the final board state is displayed along with the result.
