Argparse is a powerful and flexible command-line argument parsing library in Python. It allows you to easily handle command-line arguments and options in your scripts. In this tutorial, we'll focus on positional arguments, which are essential components of many command-line interfaces.
Positional arguments are values that are specified on the command line without any preceding flag or option. They are typically used for mandatory inputs to your script. For example, if your script expects a filename as input, you might define a positional argument for it.
Save the script and run it from the command line:
You can define multiple positional arguments in your script. Let's extend the example to accept both a source file and a destination file:
Now, you can run the script with two filenames:
Adjust the filenames accordingly.
Positional arguments are a fundamental part of command-line interfaces. With the argparse module, handling these arguments becomes straightforward and allows your scripts to accept inputs from the command line with ease. Customize the argument definitions according to your script's requirements.
