Setting up how the Python `copy` module handles my objects

Question

From the copydocumentation :

Classes can use the same interfaces to control the copy that they use to control etching.

[...]

So that a class can define its own copy implementation, it can define special methods __copy__()and__deepcopy__()

So who is this? __setstate__()and __getstate__(), which are used for etching, or __copy__()and __deepcopy__()?

Answer 1

Answer 2
