Tic-Tac-Toe (Command-Line Game)

This is a complete, 2-player Tic-Tac-Toe game that runs entirely in the terminal. It was built using object-oriented principles in Python.

This project was created to demonstrate clean code, object-oriented design, and custom exception handling.

Features

• Clean and readable 3x3 game board.
• Turn-based gameplay for 'X' and 'O'.
• Automatic detection of win conditions (horizontal, vertical, and diagonal).
• Automatic detection of a draw (tie game).
• Robust input validation.

Technical Highlights

This project demonstrates proficiency in several key Python concepts:

• Object-Oriented Programming (OOP): The entire game logic, state, and behavior are encapsulated within a TicTacToe class.
• Custom Exception Handling: The program uses custom exceptions (SquareNotEmptyError and SquareNotFoundError) to manage invalid user moves gracefully instead of crashing.
• State Management: The game board and player turns are managed cleanly within the class instance.
• Algorithmic Logic: The game_finished() method contains the core algorithm for checking all possible win/draw scenarios.
