11 Another generally useful object type is a tuple of object pointers. | |
12 For Python, this is an immutable type. C code can change the tuple items | |
13 (but not their number), and even use tuples are general-purpose arrays of | |
14 object references, but in general only brand new tuples should be mutated, | |
15 not ones that might already have been exposed to Python code. | |
16 | |
17 *** WARNING *** PyTuple_SetItem does not increment the new item's reference | |
18 count, but does decrement the reference count of the item it replaces, | |
19 if not nil. It does *decrement* the reference count if it is *not* | |
20 inserted in the tuple. Similarly, PyTuple_GetItem does not increment the | |
21 returned item's reference count. | |
