Player X's turn. Choose column (0-7):

• Check for wins after each move: The game should verify if there are four connected pieces in any direction—vertical, horizontal, or diagonal.
• Continue the game until a player wins or all spaces are filled, resulting in a draw.
• Comment your code to explain the implementation of game mechanics and logic decisions. Be careful to put relevant comments!
• Structure your code to handle game state management, user input, and display output cleanly and efficiently.

Bonus tasks

• Include error handling for invalid inputs such as entering non-numeric values, choosing columns that are out of bounds, or selecting columns that are already full.
• Enhance the game by adding colors to the discs (X and O).
• Allow the players to play multiple rounds without restarting the program.
• Improve the terminal UI to make it more user-friendly, e.g., by clearing the screen before displaying the board.

As explained in technical_structure_and_logic my playing grid is represented by a bi-dimensional array :

I also use aurora package to print elements with color in the console.
