Argparse
Argparse is a Python standard library module for parsing command-line arguments and options. It simplifies the creation of user-friendly command-line interfaces by automatically generating help messages and handling argument validation. It is widely used for building scripts and applications that require command-line input.
Developers should use Argparse when creating Python scripts or applications that need to accept command-line arguments, such as configuration settings, file paths, or flags. It is essential for building robust CLI tools, automation scripts, and data processing pipelines where user input must be parsed efficiently and error-handled. For example, it's ideal for tools like data converters, system utilities, or batch job runners.
