Remove and return an arbitrary ``(key, value)`` pair from the dictionary. Remove and return a ``(key, value)`` pair from the dictionary. Pairs are returned in :abbr:`LIFO (last-in, first-out)` order.
:meth:`popitem` is useful to destructively iterate over a dictionary, as often used in set algorithms. If the dictionary is empty, calling :meth:`popitem` raises a :exc:`KeyError`.
.. versionchanged:: 3.7
LIFO order is now guaranteed. In prior versions, :meth:`popitem` would return an arbitrary key/value pair.
