# List Objects

type PyListObject

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

PyTypeObject PyList_Type
  Bir parçası Kararlı 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)
  Döndürdüğü değer: Yeni referans. Bir parçası Kararlı ABI.

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

  Not

  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()`.

Py_ssize_t PyList_Size(PyObject *list)
  Bir parçası Kararlı 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_GetItem(PyObject *list, Py_ssize_t index)
  Döndürdüğü değer: Ödünç alınmış referans. Bir parçası Kararlı ABI.

  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.

PyObject *PyList_GET_ITEM(PyObject *list, Py_ssize_t i)
  Döndürdüğü değer: Ödünç alınmış referans.

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

int PyList_SetItem(PyObject *list, Py_ssize_t index, PyObject *item)
  Bir parçası Kararlı 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.

  Not

  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.

  Not

  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)
  Bir parçası Kararlı 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)
  Bir parçası Kararlı 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)
  Döndürdüğü değer: Yeni referans. Bir parçası Kararlı 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)
  Bir parçası Kararlı 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_Sort(PyObject *list)
  Bir parçası Kararlı 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)
  Bir parçası Kararlı 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)
  Döndürdüğü değer: Yeni referans. Bir parçası Kararlı ABI.

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