PEP 634: Structural Pattern Matching
    Patterns and classes

In the example code, x and y in the printed messages are swapped.

        case Point(x=0, y=y):
            print(f"Y={y} and the point is on the y-axis.")
        case Point(x=x, y=0):
            print(f"X={x} and the point is on the x-axis.")

Should be:

        case Point(x=0, y=y):
            print(f"Y={y} and the point is on the x-axis.")
        case Point(x=x, y=0):
            print(f"X={x} and the point is on the y-axis.")
