Step 2: Running the Tic-Tac-Toe Game

1. Open your terminal (or command prompt).
2. Navigate to the directory where you saved tic_tac_toe.py.
3. Run the script using the command:bashCopy codepython tic_tac_toe.py

How It Works

• Game Board: The board is represented as a list of strings, with ‘ ‘ indicating empty spaces.
• Player Turns: Players alternate turns, with ‘X’ and ‘O’ representing the two players.
• Move Validation: The game checks if the chosen position is valid and not already taken.
• Winning Conditions: The game checks for winning combinations after each move.
• Draw Condition: If the board is full without a winner, it announces a draw.

Example Gameplay

1. The board is displayed in a 3×3 grid.
2. Players take turns entering their moves by specifying a number from 1 to 9 corresponding to the board positions.
3. The game announces the winner or if it’s a draw.
