/* The unique ellipsis object "..." */

PyAPI_DATA(PyObject) _Py_EllipsisObject; /* Don't use this directly */

#define Py_Ellipsis (&_Py_EllipsisObject)

/* Slice object interface */

A slice object containing start, stop, and step data members (the

names are from range). After much talk with Guido, it was decided to

let these be any arbitrary python type. Py_None stands for omitted values.
