Python object deleting itself

Question

Why won\'t this work? I\'m trying to make an instance of a class delete itself.

>>> class A():
    def kill(self):
        del self


>>>

A replacement implement:

class A:

    def __init__(self):
        self.a = 123

    def kill(self):
        from itertools import chain
        for attr_name in chain(dir(self.__class__), dir(self)):
            if attr_name.startswith('__'):
                continue
            attr = getattr(self, attr_name)
            if callable(attr):
                setattr(self, attr_name, lambda *args, **kwargs: print('NoneType'))
            else:
                setattr(self, attr_name, None)
        a.__str__ = lambda: ''
        a.__repr__ = lambda: ''

a = A()
print(a.a)
a.kill()

print(a.a)
a.kill()

a = A()
print(a.a)

will outputs:

123
None
NoneType
123
