argparse.ArgumentParser

argparse.ArgumentParser is a class in the Python standard library module argparse. It is used to create an argument parser object, which is used to parse command-line arguments passed to a Python script.

The ArgumentParser class provides methods to define the arguments that the script expects, such as positional arguments, optional arguments, and flags. It also provides options to specify default values, help messages, and other configuration parameters for the arguments.

The ArgumentParser class is typically initialized with a description of the script and its arguments, which is displayed when the script is called with the "--help" option. It can then be used to parse the command-line arguments passed to the script and return the values of the arguments in a structured manner.
