Simple example of use of __setstate__ and __getstate__

Question

I don\'t know what the __setstate__ and __getstate__ methods do, so help me with a simple example.

Answer 1

These methods are used for controlling how objects are pickled and unpickled by the pickle module. This is usually handled automatically, so unless you need to override how a class is pickled or unpickled you shouldn't need to worry about it.
