I, like Diez am unsure of why you would need what you have asked for, but maybe this will help. You can keep track of all instances of a class by this kind of thing: >>> class C1(object): ... inst = [] ... def __init__(self): ... self.inst.append(self) ... >>> i1 = C1() >>> i2 = C1() >>> print i1,i2 <__main__.C1 object at 0x0128C970> <__main__.C1 object at 0x0128CA50> >>> print C1.inst [<__main__.C1 object at 0x0128C970>, <__main__.C1 object at 0x0128CA50>] >>> -- http://mail.python.org/mailman/listinfo/python-list
