Consider this simplified Python code using the Memento pattern:

class Memento:
    def __init__(self, state):
        self._state = state

class Originator:
    def __init__(self):
        self._state = ""
    def set_state(self, state):
        self._state = state
    def save(self):
        return Memento(self._state)
    def restore(self, memento):
        self._state = memento._state

originator = Originator()
originator.set_state("State1")
memento = originator.save()
originator.set_state("State2")
originator.restore(memento)
print(originator._state)

What will be printed?
