What are command-line arguments in Python?

Command-line arguments in Python refer to the parameters that can be passed to a program when it is invoked from a command line interface. This feature allows users to provide inputs to the script dynamically at runtime without modifying the code itself.

When a Python script is executed from the terminal, additional data can be appended after the script's name, and these pieces of data are treated as command-line arguments. They can be accessed within the script using the sys.argv list, where the first element is the name of the script itself, and any subsequent elements are the arguments passed.

This capability is essential for creating flexible and reusable scripts, as it allows the same script to behave differently based on the input parameters provided at the time of execution. For example, a script that processes files can accept the filename as a command-line argument, making it adaptable to different files without the need to edit the script each time.

In contrast, the other options focus on different types of arguments or specify conditions that do not qualify as command-line arguments. For instance, arguments defined within the script or hardcoded values do not have the dynamic characteristic of command-line arguments. Additionally, arguments that alter a function's return type pertain to function design rather than the context of runtime script
