What are the advanced pattern matching features in Python 3.10?

Python 3.10 introduced structural pattern matching, allowing for more expressive and readable code. You can match on data structures like lists, dictionaries, and even custom classes.

Can you give me an example of using pattern matching with a dictionary?

Sure! Here's a simple example:

match my_dict:
    case {'key1': value1, 'key2': value2}:
        print(f'Key1: {value1}, Key2: {value2}')
    case _:
        print('No match')

What about matching with lists?

You can match lists similarly. For example:

match my_list:
    case [first, second, *rest]:
        print(f'First: {first}, Second: {second}, Rest: {rest}')
    case _:
        print('No match')

Are there any limitations to pattern matching?

Yes, pattern matching can only be used with certain data types, and it may not be as efficient as traditional methods for very large datasets.
