python argparse flag

Argparse is a powerful module in Python that makes it easy to write user-friendly command-line interfaces. In this tutorial, we'll focus on using flags with argparse to handle command-line arguments in your Python scripts.
Argparse is a module in the Python standard library that simplifies the process of parsing command-line arguments. It provides a convenient way to define, validate, and manage command-line options and arguments.
If you're using Python 3.2 or later, Argparse is included in the standard library. For older versions, you can install it using pip:
Let's start with a simple example to demonstrate the basic usage of argparse with flags.

Output:
argparse.ArgumentParser is used to create a new ArgumentParser object, which will hold all the information necessary to parse the command-line arguments.
add_argument is used to specify which command-line options the program is expecting. In this example, we added a boolean flag -v or --verbose using the add_argument method.
The help parameter provides a description of the flag, which is displayed when the user runs the script with the --help option.
Argparse is a powerful tool for handling command-line arguments in Python scripts. Flags, like the --verbose example, make it easy to provide additional functionality to your scripts without cluttering the command line with unnecessary arguments. Experiment with argparse to enhance the usability of your command-line applications.
