279279 A constant value. The ``value `` attribute of the ``Constant `` literal contains the
280280 Python object it represents. The values represented can be instances of :class: `str `,
281281 :class: `bytes `, :class: `int `, :class: `float `, :class: `complex `, and :class: `bool `,

284+ The ``kind `` attribute is an optional string. For string literals with a
285+ ``u `` prefix, ``kind `` is set to ``'u' ``. For all other
286+ constants, ``kind `` is ``None ``.
