This problem has nothing to do with pickling. In general, assigning to
a parameter (even self) will not make a change that lasts after the
method call. For example:
>>> class A:
... def change(self):
... self = "something else entirely"
...
>>> a = A()
>>> a.change()
>>> a
<__main__.A instance at 0x009DCD00>
Note, however, that you can MODIFY self in-place within a method. You
can probably hack together a solution that modifies self.__dict__,
self.__class__, self.__class__.__dict__, or some other magic
properties.
