Slice Objects
*************

PyTypeObject PySlice_Type
    * Bir parçası Kararlı ABI.*

   The type object for slice objects.  This is the same as "slice" in
   the Python layer.

int PySlice_Check(PyObject *ob)

   Return true if *ob* is a slice object; *ob* must not be "NULL".
   This function always succeeds.

PyObject *PySlice_New(PyObject *start, PyObject *stop, PyObject *step)
    *Döndürdüğü değer: Yeni referans.** Bir parçası Kararlı ABI.*

   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.

   Return "NULL" with an exception set if the new object could not be
   allocated.

int PySlice_GetIndices(PyObject *slice, Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step)
    * Bir parçası Kararlı ABI.*

   Retrieve the start, stop and step indices from the slice object
   *slice*, assuming a sequence of length *length*. Treats indices
   greater than *length* as errors.

   Returns "0" on success and "-1" on error with no exception set
   (unless one of the indices was not "None" and failed to be
   converted to an integer, in which case "-1" is returned with an
   exception set).

   You probably do not want to use this function.

   3.2 sürümünde değişti: The parameter type for the *slice* parameter
   was "PySliceObject*" before.

int PySlice_GetIndicesEx(PyObject *slice, Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step, Py_ssize_t *slicelength)
    * Bir parçası Kararlı ABI.*

   Usable replacement for "PySlice_GetIndices()".  Retrieve the start,
   stop, and step indices from the slice object *slice* assuming a
   sequence of length *length*, and store the length of the slice in
   *slicelength*.  Out of bounds indices are clipped in a manner
   consistent with the handling of normal slices.

   Return "0" on success and "-1" on error with an exception set.

   Not:

     This function is considered not safe for resizable sequences. Its
     invocation should be replaced by a combination of
     "PySlice_Unpack()" and "PySlice_AdjustIndices()" where

        if (PySlice_GetIndicesEx(slice, length, &start, &stop, &step, &slicelength) < 0) {
            // return error
        }

     is replaced by

        if (PySlice_Unpack(slice, &start, &stop, &step) < 0) {
            // return error
        }
        slicelength = PySlice_AdjustIndices(length, &start, &stop, step);

   3.2 sürümünde değişti: The parameter type for the *slice* parameter
   was "PySliceObject*" before.

   3.6.1 sürümünde değişti: If "Py_LIMITED_API" is not set or set to
   the value between "0x03050400" and "0x03060000" (not including) or
   "0x03060100" or higher "PySlice_GetIndicesEx()" is implemented as a
   macro using "PySlice_Unpack()" and "PySlice_AdjustIndices()".
   Arguments *start*, *stop* and *step* are evaluated more than once.

   3.6.1 sürümünden beri kullanım dışı: If "Py_LIMITED_API" is set to
   the value less than "0x03050400" or between "0x03060000" and
   "0x03060100" (not including) "PySlice_GetIndicesEx()" is a
   deprecated function.

int PySlice_Unpack(PyObject *slice, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t *step)
    * Bir parçası Kararlı ABI 3.7 sürümünden beri.*

   Extract the start, stop and step data members from a slice object
   as C integers.  Silently reduce values larger than "PY_SSIZE_T_MAX"
   to "PY_SSIZE_T_MAX", silently boost the start and stop values less
   than "PY_SSIZE_T_MIN" to "PY_SSIZE_T_MIN", and silently boost the
   step values less than "-PY_SSIZE_T_MAX" to "-PY_SSIZE_T_MAX".

   Return "-1" with an exception set on error, "0" on success.

   Added in version 3.6.1.

Py_ssize_t PySlice_AdjustIndices(Py_ssize_t length, Py_ssize_t *start, Py_ssize_t *stop, Py_ssize_t step)
    * Bir parçası Kararlı ABI 3.7 sürümünden beri.*

   Adjust start/end slice indices assuming a sequence of the specified
   length. Out of bounds indices are clipped in a manner consistent
   with the handling of normal slices.

   Return the length of the slice.  Always successful.  Doesn't call
   Python code.

   Added in version 3.6.1.


Ellipsis Object
===============

PyObject *Py_Ellipsis

   The Python "Ellipsis" object.  This object has no methods.  Like
   "Py_None", it is an immortal. singleton object.

   3.12 sürümünde değişti: "Py_Ellipsis" is immortal.
