Changes proposed in this pull request
-CLI entry point for standalone execution.

-Better structure and readability.

-Error logging instead of silently passing.

Summary by Sourcery

Add a CLI entry point to the Example script for standalone execution and enhance its structure, readability, and error handling.

New Features:

  • Introduce a main() function and shebang to allow direct execution of the Example script
  • Wrap script logic with an if name == "main" guard to support CLI usage

Enhancements:

  • Reorganize imports, add file header comments, and set up warnings suppression
  • Configure Wikipedia language to English by default
  • Improve whoIs fallback logic to search alternative topics and return user-facing error messages instead of silent failures

Reviewer's Guide

Introduced a standalone CLI entry point by refactoring the example script into a main() function with execution guard, reorganizing imports and file header, improving error handling and adding descriptive logging.

Hey @muhannad-iz-a-tech-nerd - I've reviewed your changes - here's some feedback:

  • Consider replacing the hard-coded first question and template path with argparse or click so users can pass custom inputs via the CLI.
  • Use the logging module for error messages instead of print() to keep error handling consistent across the application.
  • To make your CLI entry point installable, consider adding a console_scripts entry in setup.py or pyproject.toml so users can invoke it directly after install.

<issue_to_address>
Early return on missing template prevents user feedback in CLI.

Recommend replacing 'return' with 'sys.exit(1)' to provide a standard error exit code for CLI tools, aiding automation and scripting.
