The ``=`` specifier can be used to expand an expression to the text of the
expression, an equal sign, then the representation of the evaluated expression:
>>> bugs = 'roaches'
>>> count = 13
>>> area = 'living room'
>>> print(f'Debugging {bugs=} {count=} {area=}')
Debugging bugs='roaches' count=13 area='living room'
See :ref:`self-documenting expressions <bpo-36817-whatsnew>` for more information
on the ``=`` specifier. For a reference on these format specifications, see
