you should see the output:
to provide a custom message, you can use the -m or --message option:
this will output:
in this tutorial, you learned how to create a simple python command-line tool using argparse. you can extend this example to build more complex cli applications by adding more commands and options. experiment with argparse to create powerful and user-friendly command-line interfaces for your python programs.
