python argparse possible values

The argparse module in Python is a powerful tool for parsing command-line arguments and options. In this tutorial, we will explore how to use argparse to handle possible values for command-line arguments. This is useful when you want to restrict the input to a predefined set of values.
Before we begin, make sure you have Python installed on your system. Python usually comes with argparse as part of the standard library, so there's no need to install anything additional.
Let's start with a basic example of using argparse without restricting the possible values. We'll then modify it to include predefined choices.
Now, let's modify our script to include possible values for the input argument.
If you try to input a value not in the specified choices, argparse will raise an error.
argparse is a versatile module that allows you to handle command-line arguments efficiently. By incorporating possible values, you can ensure that users provide valid inputs, reducing the chances of errors in your scripts. Feel free to customize and extend this tutorial to fit your specific needs.
