OK, you will use something like this:

class AAA (object):
    counter = 0
    def __new__(cls):
        cls.counter += 1
        return super(cls, cls).__new__(cls)

but I think that __new__ is more "low level" and not necessary here,
so I will use:

class AAA (object):
    counter = 0
    def __init__(self):
        self.counter_increase()
    @classmethod
    def counter_increase(cls):
        cls.counter += 1

with yours correction invoking self.counter_increase() instead of more
explicit type(self).counter_increase()
