Refactored example.py for improved readability and structure

[Muneer320]

Overview:

This PR refactors the example.py file by organizing the previous script into multiple functions for enhanced readability and better structure.

Changes Made:

• Separated examples into distinct functions such as:
  • display_subreddit_posts()
  • save_subreddit_data()
  • download_subreddit_images()
  • display_search_results()
  • display_user_data()
  • display_post_comments()
• Simplified variable naming and made the code easier to follow.
• Ensured that each function focuses on a specific task, improving both modularity and maintainability.
• Retained the original logic and added no new functionality, strictly focused on code readability.
