Today is a great day to learn about #Python's `argparse` module!

The argparse module makes it easy to write user-friendly command-line interfaces.

Here is an example of creating an argument parser with no arguments.

Why would you do that? Well, to find out what `argparse` gives you out of the box 📦!

You can see here that `argparse` gives you some help text and prints out your provided description

A common coding pattern for argument parsing is to put the argument parsing code into its own function or method and then return the parsed args.

Here's an example:

Let's add some arguments to our argument parser! In this example, you add one required argument and two optional arguments.

One of the optional arguments shows you how to apply a default value while the other only accepts integers

You can use short argument flags or long argument flags with #Python's `argparse` module 🐍🔥

This thread only scratches the surface of what you can do with Python's `argparse` module.

Check out the docs for lots more detail:
