What are some examples of pattern matching in Python 3.10?

In Python 3.10, pattern matching allows you to match data structures against patterns. For example, you can use it with lists, dictionaries, and classes.

Can you show me a simple example using a list?

Sure! Here's a simple example:

match my_list:
    case [1, 2, 3]:
        print('Matched the list [1, 2, 3]!')
    case _:
        print('No match found.')

What about using pattern matching with dictionaries?

You can match dictionaries like this:

match my_dict:
    case {'key1': value1, 'key2': value2}:
        print(f'Matched with key1: {value1} and key2: {value2}')
    case _:
        print('No match found.')

Are there any limitations to pattern matching?

Yes, pattern matching in Python 3.10 has some limitations, such as not being able to match against certain complex data types directly.
