/* Tuple object interface */

/*
|
|
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.
