python argparse subparser

Показать описание
Argparse is a Python module for parsing command-line arguments and generating help messages. Subparsers are a powerful feature of argparse that allows you to create command-line interfaces with multiple subcommands. This tutorial will guide you through the process of using argparse subparsers with a detailed code example.
First, you need to import the argparse module.
Create an ArgumentParser object, which will hold all the information necessary to parse the command-line arguments.
You can add global arguments that apply to all subcommands using the add_argument method.
Create subparsers using the add_subparsers method.
Add individual subcommands using the add_parser method on the subparsers object.
Parse the command-line arguments using the parse_args method.
Access the parsed arguments using the dot notation.
Save your script and run it from the command line.
This example runs the script with "subcommand1," providing the required argument 42 and enabling the verbose mode.
That's it! You have successfully created a Python script with argparse subparsers. Customize the script and subcommands based on your specific use case.
