[New-bugs-announce] [issue43310] Method __del__ with callable

[Andrey Petukhov]

New submission from Andrey Petukhov <andribas404 at gmail.com>:

Is it possible to use callable to replace __del__ method of class?

if so, how to get self variable?

class A(object):
    """A."""


class C(object):
    """Callable."""
    def __call__(self, *args, **kwargs):
        print("call", args, kwargs)


def func_del(*args, **kwargs):
    """Method."""
    print("func", args, kwargs)


def del_function():
    """
    Test del.

    ('func', (<__main__.A object at 0x7f8ae5a82750>,), {})
    ('call', (), {})
    """
    c = C()
    A.__del__ = func_del
    a = A()
    del a
    A.__del__ = c
    a = A()
    del a
