The question is: How do i move the 'do' method from A to b

If you want to move the method from class A to class B
(which is normally more sensible than to instance b of B)
B.do = A.do.im_func # Python 2
B.do = A.do # Python 3
b = B()
b.do()
# print (with print adjusted for PY3)
A.do: self.name = b
If you want a B instance to act like an A instance, you can change its
class (subject to some limitations). The following works.
b = B()
b.__class__ = A
b.do()
If make the change temporary and the reversion automatic, write a
context manager.
