|
Another generally useful object type is a tuple of object pointers. |
|
For Python, this is an immutable type. C code can change the tuple items |
|
(but not their number), and even use tuples are general-purpose arrays of |
|
object references, but in general only brand new tuples should be mutated, |
|
not ones that might already have been exposed to Python code. |
|
|
|
*** WARNING *** PyTuple_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 tuple. Similarly, PyTuple_GetItem does not increment the |
|
returned item's reference count. |
