I'm not sure I understand what you mean, it sounds like you want something
like "singleton methods"?  In any case, you could perhaps simulate that with
default args:

>>> class A:
...     def __init__(self):
...         self.val = 0
...     def meth(self):
...         return self.val
...
>>> a = A()
>>> a.meth2 = lambda self=a: self.val + 1
>>> a.meth2()
1
