>>> class Parrot:
... def hello(self):
... print("Hello")
... def delete_this(self):
... self.__class__ = DeadParrot
...
>>> class DeadParrot:
... def __getattr__(self, name):
... raise Exception("This parrot is no more")
...
>>> p = Parrot()
>>> p.hello()
Hello
>>> p.delete_this()
>>> p.hello()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in __getattr__
Exception: This parrot is no more
But I don't think it's a good idea...
