我试图运行文档中的示例，但出现错误：

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
TypeError: Point() accepts 0 positional sub-patterns (2 given)

有人可以解释我在这里做错了什么吗？

class Point():
    def __init__(self, x, y):
            self.x = x
            self.y = y

x, y = 5 ,5
point = Point(x, y)
match point:
    case Point(x, y) if x == y:
        print(f"Y=X at {x}")
    case Point(x, y):
        print(f"Not on the diagonal")
