Sequence Types --- :class:`str`, :class:`bytes`, :class:`bytearray`, :class:`list`, :class:`tuple`, :class:`range`
==================================================================================================================
-There are six sequence types: strings, byte sequences, byte arrays, lists,
-tuples, and range objects. (For other containers see the built-in
