You are sharing this single "sub" dictionary with all instances of your
A class.

If you want to define instance-specific attributes, define them in the
__init__ method, like so:

class A:
    def __init__(self):
        self.sub = dict()

    def sub_add(self, cls):
        obj = cls()
        self.sub[obj.id] = obj
