argparse.ArgumentParser

argparse.ArgumentParser is a class in the Python argparse module that is used to create an argument parser object. An argument parser object is used to parse command-line arguments and options provided by the user when executing a Python script.

The ArgumentParser class provides a number of methods to define the arguments that can be passed to the script, such as add_argument() and add_mutually_exclusive_group(). It also provides methods to customize the help message that is displayed to the user, such as description and epilog.

The ArgumentParser class is typically used to define the command-line interface of a Python script. It allows the script to accept input from the user in a standardized and easy-to-use way, and provides a consistent interface across different operating systems and environments.
