        class HypotPoint(namedtuple('Point', 'x y')):
            @property
            def hypot(self):
                return (self.x**2 + self.y**2)**0.5

            def __str__(self):
                return 'Point: x=%6.3f y=%6.3f hypot=%6.3f' % (self.x, self.y,
                                                               self.hypot)

Example #2

        class OptimizedPoint(namedtuple('Point', 'x y')):
            _make = classmethod(tuple.__new__)

            def _replace(self, _map=map, **kwds):
                return self._make(_map(kwds.get, ('x', 'y'), self))
