How can I use pattern matching in Python?

You can use the match statement introduced in Python 3.10 for pattern matching. It allows you to match values against patterns.

Can you give me an example of how it works?

Sure! Here's a simple example:

def match_shape(shape):
    match shape:
        case ('circle', radius):
            return f'Circle with radius {radius}'
        case ('square', side):
            return f'Square with side {side}'
        case _:
            return 'Unknown shape'

You can call match_shape(('circle', 5)) to get 'Circle with radius 5'.

What are the benefits of using pattern matching?

Pattern matching makes your code cleaner and more readable, especially when dealing with complex data structures. It also allows for more expressive handling of different cases.
