PyListObject
This subtype of
represents a Python list object.
PyList_Type
This instance of
represents the Python list type. This is the same object as
in the Python layer.
int PyList_Check(
*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(
*p)
Return true if p is a list object, but not an instance of a subtype of the list type. This function always succeeds.
* PyList_New(
len)
Return value: New reference.Return a new list of length len on success, or NULL on failure.
Note
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
or expose the object to Python code before setting all items to a real object with
.
PyList_Size(
*list)
Return the length of the list object in list; this is equivalent to len(list) on a list object.
PyList_GET_SIZE(
*list)
Macro form of
without error checking.
* PyList_GetItem(
*list,
index)
Return value: Borrowed reference.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
exception.
* PyList_GET_ITEM(
*list,
i)
Return value: Borrowed reference.Macro form of
without error checking.
int PyList_SetItem(
*list,
index,
*item)
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
exception.
Note
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(
*list,
i,
*o)
Macro form of
without error checking. This is normally only used to fill in new lists where there is no previous content.
Note
This macro “steals” a reference to item, and, unlike
, 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(
*list,
index,
*item)
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(
*list,
*item)
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).
* PyList_GetSlice(
*list,
low,
high)
Return value: New reference.Return a list of the objects in list containing the objects betweenlow 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(
*list,
low,
high,
*itemlist)
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(
*list)
Sort the items of list in place. Return 0 on success, -1 on failure. This is equivalent to list.sort().
int PyList_Reverse(
*list)
Reverse the items of list in place. Return 0 on success, -1 on failure. This is the equivalent of list.reverse().
* PyList_AsTuple(
*list)
Return value: New reference.Return a new tuple object containing the contents of list; equivalent to tuple(list).
