What are pattern matching classes in Python 3.10?

Pattern matching classes in Python 3.10 allow you to match data structures against patterns, making code more readable.

Can you give me an example of how to use pattern matching with classes?

Sure! Here's a simple example:

class Shape:
    pass

class Circle(Shape):
    def __init__(self, radius):
        self.radius = radius

class Square(Shape):
    def __init__(self, side):
        self.side = side

def describe_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"

What are the benefits of using pattern matching over traditional if-else statements?

Pattern matching is more concise and expressive, allowing for clearer intent and easier maintenance of the code.

Are there any limitations to pattern matching in Python 3.10?

Yes, while powerful, pattern matching has limitations such as not supporting all data types and being less flexible than some dynamic approaches.
