Raymond Hettinger added the comment:
Possibly __getstate__ could be removed. That said, I would feel a sense of
risk in taking it out -- that method has been present for a *very* long time
who knows what might rely on it being there.

__getstate__ is for pickling instances [0], __reduce__ is for pickling the
object itself [1]

Víctor Terrón added the comment:
Ramchandra, that is not the behavior that I am able to reproduce. Please see
the attached example: in the presence of __reduce__(), __getstate__() is not
being called whether the class or an instance its pickled. This is also in
consonance with what is stated

New submission from Víctor Terrón:
The random.Random class implements both the __getstate__() and __reduce__()
methods. My knowledge of the pickle module is very limited, but apparently this
causes __getstate__() never to get called. Maybe this is a remnant from earlier
code, or are both
