python argparse default value

The argparse module in Python provides a convenient way to parse command-line arguments. In this tutorial, we'll focus on setting default values for command-line arguments using argparse. Default values allow you to define a value that will be used if the user does not provide a specific argument on the command line.
Start by importing the argparse module in your Python script:
Create an ArgumentParser object, which will handle the command-line argument parsing for you:
You can add command-line arguments using the add_argument method of the ArgumentParser object. Set the default parameter to specify the default value:
In this example, we have three arguments:
Parse the command-line arguments using the parse_args method:
Now, args will contain the values specified by the user on the command line or the default values if not provided.
Access the values of the parsed arguments through the args object:
Here's the complete script:
Save the script and run it from the command line:
If no values are provided, the script will use the default values:
This tutorial should help you understand how to use default values with argparse in Python for handling command-line arguments effectively.
