Как написать неизменяемый класс

class Immutable:
    __slots__ = ('_value',)
    
    def __init__(self, value):
        super().__setattr__('_value', value)
    
    @property
    def value(self):
        return self._value
    
    def __setattr__(self, name, value):
        raise AttributeError("Immutable objects can't be modified")

from collections import namedtuple

ImmutablePoint = namedtuple('ImmutablePoint', ['x', 'y'])

from dataclasses import dataclass

@dataclass(frozen=True)
class ImmutableData:
    field1: str
    field2: int
