How to use command line arguments in a Python script with sys.argv and argparse

This video tutorial explores how to use command line arguments in Python scripts. It begins with a basic introduction to sys.argv, demonstrating how to access and use command line arguments. The tutorial then highlights the limitations of sys.argv for complex tasks and introduces the argparse module as a more robust solution. Through examples, it shows how argparse simplifies argument handling, provides automatic help messages, and supports both positional and optional arguments. The video concludes by comparing the benefits of using argparse over sys.argv.
