Comment code generate a tutorial

Transform this Python script into a polished, beginner-friendly project by refactoring the code, adding clear instructional comments, and generating a complete markdown tutorial.

1. Refactor the code

   • Apply standard Python best practices
   • Ensure code follows the PEP 8 style guide
   • Rename unclear variables and functions if needed for clarity

2. Add comments throughout the code

   • Use a beginner-friendly, instructional tone
   • Explain what each part of the code is doing and why it's important

   Include the following sections:

   • Project Overview: What the script does and why it's useful
   • Setup Instructions: Prerequisites, dependencies, and how to run the script
   • How It Works: A breakdown of the code logic based on the comments
   • Example Usage: A code snippet showing how to use it
   • Sample Output: (Optional) Include if the script returns visible results
