How to Access and Use Command Line Arguments in Python?

Command Line Arguments with Python

Question: How can we access and interpret command line arguments provided for a Python script?

Context:

Command line arguments allow users to configure a script's behavior when invoked. It's a common feature of many programs.

Processing Command Line Arguments:

In Python, the sys.argv variable holds a list of command line arguments. sys.argv[0] always represents the script name itself.

To process the arguments, you can iterate over sys.argv[1:], which contains the actual arguments provided. For instance:

import sys

print("\n".join(sys.argv))

This code prints each argument on a new line.

Alternatively, you can access specific arguments by their index:

import sys

print(sys.argv[1:])

This code prints only the user-provided arguments, excluding the script name.
