When it comes to writing versatile and user-friendly Python scripts, knowing how to handle command-line arguments is invaluable. These small, powerful tools enable users to control how a script behaves without modifying code. Python’s argparse library is built precisely for this purpose, and it simplifies the process significantly. In this guide, I’ll walk you through
