C code can change the tuple items 12(but not their number), and even use tuples as general-purpose arrays of 13object references, but in general only brand new tuples should be mutated, 14not ones that might already have been exposed to Python code. 15 16*** WARNING *** PyTuple_SetItem does not increment the new item's reference 17count, but does decrement the reference count of the item it replaces, 18if not nil. It does *decrement* the reference count if it is *not* 19inserted in the tuple. Similarly, PyTuple_GetItem does not increment the 20returned item's reference count. 21*/ 22 23PyAPI_DATA(PyTypeObject) PyTuple_Type; 24PyAPI_DATA(PyTypeObject) PyTupleIter_Type; 25 26#define PyTuple_Check(op) \ 27 PyType_FastSubclass(Py_TYPE(op), Py_TPFLAGS_TUPLE_SUBCLASS) 28#define PyTuple_CheckExact(op) Py_IS_TYPE(op, &PyTuple_Type) 29 30PyAPI_FUNC(PyObject *) PyTuple_New(Py_ssize_t size); 31PyAPI_FUNC(Py_ssize_t) PyTuple_Size(PyObject *); 32PyAPI_FUNC(PyObject *) PyTuple_GetItem(PyObject *, Py_ssize_t); 33PyAPI_FUNC(int) PyTuple_SetItem(PyObject *, Py_ssize_t, PyObject *); 34PyAPI_FUNC(PyObject *) PyTuple_GetSlice(PyObject *, Py_ssize_t, Py_ssize_t); 35PyAPI_FUNC(PyObject *) PyTuple_Pack(Py_ssize_t, ...); 36 37#ifndef Py_LIMITED_API 38# define Py_CPYTHON_TUPLEOBJECT_H 39# include "cpython/tupleobject.h" 40# undef Py_CPYTHON_TUPLEOBJECT_H 41#endif 42 43#ifdef __cplusplus 44} 45#endif 46#endif /* !Py_TUPLEOBJECT_H */ 47
