Error handling, spots for docstrings and differentiating 'message' and 'messages' variables in question_wizard.py

[Taehyun-Alex]

Enhancements for code clarity and consistency within the Python files

Details

1. Error handling messages

• SyntaxError in function, 'wrapped_callback' could use a detailed error message for better clarity
  
• ValueError in function input_callback could use a detailed error message for better clarity
  

2. Docstrings for Python codes

• The functions throughout the Python files could use docstrings for a better understanding of the code.

3. Variable naming consistency in question_wizard.py

• In the question_wizard_check function, we have both 'messages' and 'message' as variables. Ensure consistency in variable names to avoid confusion.
