python argparse string

Argparse is a built-in module in Python that makes it easy to write user-friendly command-line interfaces. It allows you to define command-line options, arguments, and subcommands for your Python scripts. In this tutorial, we'll explore the basics of using argparse with a focus on handling string arguments.
Argparse comes pre-installed with Python, so you don't need to install anything extra.
In this example, we've created a script that takes a single positional argument (input_string). The argparse.ArgumentParser class is used to define the command-line interface for your script. The parse_args() method is then called to parse the command-line arguments.
Replace "Hello, argparse!" with any string you want to use as input. The script will print the input string.
You can also add optional arguments to your script. Let's modify the script to include an optional argument for specifying the output file:
Now you can run the script with or without the output option:
