As a Python developer, you’ll often find yourself creating scripts that need to be customized or configured based on user input. This is where command-line arguments come in handy. Command-line arguments allow you to pass values to your Python scripts from the terminal, making them more flexible and adaptable to different use cases.
In this article, we’ll explore the basics of working with command-line arguments in Python, and provide you with practical examples to help you get started.
