/* List object interface */ /* Another generally useful object type is a list of object pointers. This is a mutable type: the list items can be changed, and items can be added or removed. Out-of-range indices or non-list objects are ignored. *** WARNING *** PyList_SetItem does not increment the new item's reference count, but does decrement the reference count of the item it replaces, if not nil. It does *decrement* the reference count if it is *not* inserted in the list.
