argparse

argparse is a Python standard library module for parsing command-line arguments and options. It provides a way to define the expected arguments for a script, automatically generates help and usage messages, and handles errors for invalid inputs. It is commonly used to create user-friendly command-line interfaces for Python applications.

Also known as: argparse module, Python argparse, argparse library, command-line argument parser, CLI parser

Why learn argparse?

Developers should use argparse when building command-line tools or scripts that require user input via arguments, as it simplifies argument parsing, validation, and documentation. It is particularly useful for creating scripts with multiple options, flags, or subcommands, such as data processing tools, automation scripts, or CLI applications, ensuring robust and maintainable code.
