7.5.7 Slice Objects

PyTypeObject `PySlice_Type`
  The type object for slice objects. This is the same as `types.SliceType`.

int `PySlice_Check`(PyObject *ob)
  Returns true if ob is a slice object; ob must not be `NULL`.

PyObject* `PySlice_New`(PyObject *start, PyObject *stop, PyObject *step)
  Return value: New reference.
  Return a new slice object with the given values. The start, stop, and step parameters are used as the values of the slice object attributes of the same names. Any of the values may be `NULL`, in which case the `None` will be used for the corresponding attribute. Returns `NULL` if the new object could not be allocated.

int `PySlice_GetIndices`(PySliceObject *slice, int length, int *start, int *stop, int *step)
