This feature can be particularly beneficial when working with JSON data or nested dictionaries, common in data science projects. Consider the following example demonstrating pattern matching in Python 3.12:

def process_data(data):
    match data:
        case {'type': 'A', 'value': val}:
            return f"Type A with value {val}"
        case {'type': 'B', 'value': val}:
            return f"Type B with value {val}"
        case _:
            return "Unknown type"

Additionally, Python 3.12 improves usability by optimizing the performance of frequently used functions and libraries, such as NumPy and Pandas.
