What are some tips for using pattern matching in Python 3.11?

In Python 3.11, pattern matching is powerful! Start by using the match statement for cleaner code. You can match on types, values, and even structures.

Can you give an example of a pattern match?

Sure! Here's a simple example:

match value:
    case 1:
        print('One')
    case 2:
        print('Two')
    case _:
        print('Something else')
``` This matches the variable `value` against the cases.

What about matching complex data structures?

You can match complex structures like lists or dictionaries. For example:

match data:
    case {'key': value}:
        print(f'Found key with value: {value}')
    case [x, y]:
        print(f'Matched a list with elements: {x} and {y}')
``` This allows for very flexible matching!

Are there any performance considerations?

Yes, while pattern matching is powerful, it can be less performant than traditional if-else chains for very simple conditions. Always consider readability and maintainability!
