Another generally useful object type is an tuple of object pointers. |
|
This is a mutable type: the tuple items can be changed (but not their |
|
number). Out-of-range indices or non-tuple objects are ignored. |

*** 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. |
