List Objects
************

type PyListObject

   This subtype of "PyObject" represents a Python list object.

PyTypeObject PyList_Type
    * Μέρος του Σταθερό ABI.*

   This instance of "PyTypeObject" represents the Python list type.
   This is the same object as "list" in the Python layer.

int PyList_Check(PyObject *p)

   Return true if *p* is a list object or an instance of a subtype of
   the list type.  This function always succeeds.

int PyList_CheckExact(PyObject *p)

   Return true if *p* is a list object, but not an instance of a
   subtype of the list type.  This function always succeeds.

PyObject *PyList_New(Py_ssize_t len)
    *Επιστρεφόμενη τιμή: New reference.** Μέρος του Σταθερό ABI.*

   Return a new list of length *len* on success, or "NULL" on failure.

   Σημείωση:

     If *len* is greater than zero, the returned list object's items
     are set to "NULL". Thus you cannot use abstract API functions
     such as "PySequence_SetItem()" or expose the object to Python
     code before setting all items to a real object with
     "PyList_SetItem()" or "PyList_SET_ITEM()". The following APIs are
     safe APIs before the list is fully initialized:
     "PyList_SetItem()" and "PyList_SET_ITEM()".

Py_ssize_t PyList_Size(PyObject *list)
    * Μέρος του Σταθερό ABI.*

   Return the length of the list object in *list*; this is equivalent
   to "len(list)" on a list object.

Py_ssize_t PyList_GET_SIZE(PyObject *list)

   Similar to "PyList_Size()", but without error checking.

PyObject *PyList_GetItemRef(PyObject *list, Py_ssize_t index)
    *Επιστρεφόμενη τιμή: New reference.** Μέρος του Σταθερό ABI από
   την έκδοση 3.13.*

   Return the object at position *index* in the list pointed to by
   *list*.  The position must be non-negative; indexing from the end
   of the list is not supported.  If *index* is out of bounds ("<0 or
   >=len(list)"), return "NULL" and set an "IndexError" exception.

   Added in version 3.13.

PyObject *PyList_GetItem(PyObject *list, Py_ssize_t index)
    *Επιστρεφόμενη τιμή: Borrowed reference.** Μέρος του Σταθερό ABI.*

   Like "PyList_GetItemRef()", but returns a *borrowed reference*
   instead of a *strong reference*.

PyObject *PyList_GET_ITEM(PyObject *list, Py_ssize_t i)
    *Επιστρεφόμενη τιμή: Borrowed reference.*

   Similar to "PyList_GetItem()", but without error checking.

int PyList_SetItem(PyObject *list, Py_ssize_t index, PyObject *item)
    * Μέρος του Σταθερό ABI.*

   Set the item at index *index* in list to *item*.  Return "0" on
   success. If *index* is out of bounds, return "-1" and set an
   "IndexError" exception.

   Σημείωση:

     This function "steals" a reference to *item* and discards a
     reference to an item already in the list at the affected
     position.

void PyList_SET_ITEM(PyObject *list, Py_ssize_t i, PyObject *o)

   Macro form of "PyList_SetItem()" without error checking. This is
   normally only used to fill in new lists where there is no previous
   content.

   Bounds checking is performed as an assertion if Python is built in
   debug mode or "with assertions".

   Σημείωση:

     This macro "steals" a reference to *item*, and, unlike
     "PyList_SetItem()", does *not* discard a reference to any item
     that is being replaced; any reference in *list* at position *i*
     will be leaked.

int PyList_Insert(PyObject *list, Py_ssize_t index, PyObject *item)
    * Μέρος του Σταθερό ABI.*

   Insert the item *item* into list *list* in front of index *index*.
   Return "0" if successful; return "-1" and set an exception if
   unsuccessful. Analogous to "list.insert(index, item)".

int PyList_Append(PyObject *list, PyObject *item)
    * Μέρος του Σταθερό ABI.*

   Append the object *item* at the end of list *list*. Return "0" if
   successful; return "-1" and set an exception if unsuccessful.
   Analogous to "list.append(item)".

PyObject *PyList_GetSlice(PyObject *list, Py_ssize_t low, Py_ssize_t high)
    *Επιστρεφόμενη τιμή: New reference.** Μέρος του Σταθερό ABI.*

   Return a list of the objects in *list* containing the objects
   *between* *low* and *high*.  Return "NULL" and set an exception if
   unsuccessful.  Analogous to "list[low:high]".  Indexing from the
   end of the list is not supported.

int PyList_SetSlice(PyObject *list, Py_ssize_t low, Py_ssize_t high, PyObject *itemlist)
    * Μέρος του Σταθερό ABI.*

   Set the slice of *list* between *low* and *high* to the contents of
   *itemlist*.  Analogous to "list[low:high] = itemlist". The
   *itemlist* may be "NULL", indicating the assignment of an empty
   list (slice deletion). Return "0" on success, "-1" on failure.
   Indexing from the end of the list is not supported.

int PyList_Extend(PyObject *list, PyObject *iterable)

   Extend *list* with the contents of *iterable*.  This is the same as
   "PyList_SetSlice(list, PY_SSIZE_T_MAX, PY_SSIZE_T_MAX, iterable)"
   and analogous to "list.extend(iterable)" or "list += iterable".

   Raise an exception and return "-1" if *list* is not a "list"
   object. Return 0 on success.

   Added in version 3.13.

int PyList_Clear(PyObject *list)

   Remove all items from *list*.  This is the same as
   "PyList_SetSlice(list, 0, PY_SSIZE_T_MAX, NULL)" and analogous to
   "list.clear()" or "del list[:]".

   Raise an exception and return "-1" if *list* is not a "list"
   object.  Return 0 on success.

   Added in version 3.13.

int PyList_Sort(PyObject *list)
    * Μέρος του Σταθερό ABI.*

   Sort the items of *list* in place.  Return "0" on success, "-1" on
   failure.  This is equivalent to "list.sort()".

int PyList_Reverse(PyObject *list)
    * Μέρος του Σταθερό ABI.*

   Reverse the items of *list* in place.  Return "0" on success, "-1"
   on failure.  This is the equivalent of "list.reverse()".

PyObject *PyList_AsTuple(PyObject *list)
    *Επιστρεφόμενη τιμή: New reference.** Μέρος του Σταθερό ABI.*

   Return a new tuple object containing the contents of *list*;
   equivalent to "tuple(list)".
