Right. > there a universally accepted code for each method? If so, what is it? > If there is no standard, what works? Lots of things work, the simplest is something like: >>> class wehaveslots(object): ... __slots__ = 'a', 'b', 'c' ... def __getstate__(self): return self.a, self.b, self.c ... def __setstate__(self, tup): self.a, self.b, self.c = tup (plus presumably other methods, but those don't matter for pickle).
