Subject: [PATCH] sudoku_game_refactor_and_fix.py

This commit includes several significant updates and enhancements to the Sudoku game script. The primary focus was on refactoring to improve code readability and maintainability, as well as resolving key issues identified in the script.

Issues Resolved:

1. Cognitive Complexity:
   - Issue: The original function `play` had a high cognitive complexity score of 20, which was above the recommended limit of 15. This complexity made the code harder to understand and maintain.
   - Resolution: The function was refactored into smaller, more manageable functions to reduce complexity. This refactoring involved breaking down the logic for calculating positions, initializing squares, and handling game updates into separate functions.

2. Import Errors:
   - Issue: The script had a missing import error for the `pygame` module, which was essential for the graphical user interface of the game.
   - Resolution: Instructions were added to ensure that `pygame` is installed and available in the environment. This included suggesting the installation of the `pygame` package using `pip`.

Updates Made:

1. Code Refactoring:
   - The `play` function was decomposed into multiple helper functions:
     - `calculate_start_position(x, y)`: Calculates the starting X and Y positions for drawing the Sudoku squares based on their coordinates.
     - `create_sudoku_squares(values)`: Initializes Sudoku square objects based on the provided values.
     - `update_display(screen, background_image, squares)`: Updates the display with the current state of the Sudoku squares.
   - This refactoring reduced the cognitive complexity of the main function and improved code readability.

2. Error Handling:
   - Improved the handling of the end-of-game condition to ensure the game exits gracefully when all assignments are processed.
   - Added an explicit check for closing the game window to ensure the script exits properly.

3. Code Optimization:
   - Consolidated repetitive logic into reusable functions to avoid redundancy and enhance maintainability.
   - Optimized the game loop and drawing operations to ensure smooth performance.

4. Added Comments and Documentation:
   - Added comments to explain the purpose of each function and major code block, making the script easier to understand and maintain for future developers.

These changes aim to enhance the overall quality of the Sudoku game script, making it more efficient, maintainable, and user-friendly.
