List(串列)物件

type PyListObject

This subtype of PyObject represents a Python list object.

PyTypeObject PyList_Type
Part of the Stable 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)

如果 p 是一個 list 物件或者是 list 型別的子型別的實例,就回傳 true。這個函式永遠會成功執行。

int PyList_CheckExact(PyObject *p)

如果 p 是一個 list 物件但不是 list 型別的子型別的實例,就回傳 true。這個函式永遠會成功執行。

PyObject *PyList_New(Py_ssize_t len)
回傳值:新的參照。 Part of the Stable ABI.

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

備註

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)
Part of the Stable 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)

PyList_Size() 類似,但沒有錯誤檢查。

PyObject *PyList_GetItem(PyObject *list, Py_ssize_t index)
回傳值:借用參照。 Part of the Stable 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)
回傳值:借用參照。

Similar to PyList_GetItem(), but without error checking.

int PyList_SetItem(PyObject *list, Py_ssize_t index, PyObject *item)
Part of the Stable 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.

備註

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.

備註

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)
Part of the Stable 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)
Part of the Stable 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)
回傳值:新的參照。 Part of the Stable 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)
Part of the Stable 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)
Part of the Stable 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)
Part of the Stable 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)
回傳值:新的參照。 Part of the Stable ABI.

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