5 Another generally useful object type is an list of object pointers. | |
6 This is a mutable type: the list items can be changed, and items can be | |
7 added or removed. Out-of-range indices or non-list objects are ignored. | |
8 | |
9 *** WARNING *** PyList_SetItem does not increment the new item's reference | |
10 count, but does decrement the reference count of the item it replaces, | |
11 if not nil. It does *decrement* the reference count if it is *not* | |
12 inserted in the list. Similarly, PyList_GetItem does not increment the | |
13 returned item's reference count. | |
