A fully interactive two-player Tic Tac Toe game running in the terminal, built in Python using functions and simple data types.
- Two-player mode (Player X vs Player O)
- Live board display that updates after each move
- Input validation — rejects invalid or already-taken squares
- Automatic win detection for rows, columns and diagonals
- Draw detection when the board is full
- Play again prompt at the end of each game
- Python 3.8 or higher

python main.py
Players take turns entering a number from 1–9 corresponding to a position on the board:
7 | 8 | 9
The first player to get three in a row (horizontally, vertically or diagonally) wins. If all squares are filled with no winner, the game ends in a draw.
