9 .. cvar:: PyTypeObject PySlice_Type
11 .. index:: single: SliceType (in module types)
13 The type object for slice objects. This is the same as ``slice`` and
17 .. cfunction:: int PySlice_Check(PyObject *ob)
19 Return true if *ob* is a slice object; *ob* must not be *NULL*.
22 .. cfunction:: PyObject* PySlice_New(PyObject *start, PyObject *stop, PyObject *step)
24 Return a new slice object with the given values. The *start*, *stop*, and
25 *step* parameters are used as the values of the slice object attributes of
26 the same names. Any of the values may be *NULL*, in which case the
27 ``None`` will be used for the corresponding attribute. Return *NULL* if
28 the new object could not be allocated.
31 .. cfunction:: int PySlice_GetIndices(PySliceObject *slice, Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step)
33 Retrieve the start, stop and step indices from the slice object *slice*,
34 assuming a sequence of length *length*. Treats indices greater than
37 Returns 0 on success and -1 on error with no exception set (unless one of
38 the indices was not :const:`None` and failed to be converted to an integer,
39 in which case -1 is returned with an exception set).
41 You probably do not want to use this function.
44 .. cfunction:: int PySlice_GetIndicesEx(PySliceObject *slice, Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step, Py_ssize_t *slicelength)
46 Usable replacement for :cfunc:`PySlice_GetIndices`. Retrieve the start,
47 stop, and step indices from the slice object *slice* assuming a sequence of
48 length *length*, and store the length of the slice in *slicelength*. Out
49 of bounds indices are clipped in a manner consistent with the handling of
52 Returns 0 on success and -1 on error with exception set.
