Document the tictactoe.py Script

[eberjohns]

This sub-issue focuses on adding comprehensive documentation directly within the tictactoe.py Python script. This will involve adding comments and docstrings to explain the purpose, functionality, parameters, and return values (if any) of each function and significant code block.

Specific Areas to Document:

• File-level docstring: A brief overview at the beginning of the script explaining its overall purpose (e.g., "A simple text-based Tic Tac Toe game where the player competes against a random computer opponent.").
• Function docstrings: For each function (display_board, enter_move, victory_for, draw_move), add a docstring that clearly explains:
  • What the function does.
  • What parameters it accepts (if any), their types, and their purpose.
  • What the function returns (if anything) and its type.
• In-line comments: Add comments within the function bodies to explain complex logic, the purpose of specific code sections, and any non-obvious steps. Focus on clarifying the "why" behind the code.
• Explanation of the board data structure: Briefly comment on how the 2D list board is used to represent the game state and how the initial numbers are used for player input.
• Comments in the main game loop: Add comments to explain the flow of the game, how turns are managed, and how the win/draw conditions are checked.

Acceptance Criteria:

• The tictactoe.py file includes a clear file-level docstring.
• Each function within the script has a comprehensive docstring explaining its purpose, parameters, and return value.
• Key sections of the code within the functions and the main game loop are well-commented to explain the logic.
• The documentation follows standard Python docstring conventions (e.g., using triple quotes).
