# Tuples
############################################################################
bint PyTuple_Check(object p)
# Return true if p is a tuple object or an instance of a subtype
# of the tuple type.
bint PyTuple_CheckExact(object p)
# Return true if p is a tuple object, but not an instance of a subtype of the tuple type.
tuple PyTuple_New(Py_ssize_t len)
# Return value: New reference.
# Return a new tuple object of size len, or NULL on failure.
tuple PyTuple_Pack(Py_ssize_t n, ...)
# Return value: New reference.
# Return a new tuple object of size n, or NULL on failure. The
# tuple values are initialized to the subsequent n C arguments
# pointing to Python objects. "PyTuple_Pack(2, a, b)" is
# equivalent to "Py_BuildValue("(OO)", a, b)".
Py_ssize_t PyTuple_Size(object p) except -1
# Take a pointer to a tuple object, and return the size of that tuple.
Py_ssize_t PyTuple_GET_SIZE(object p)
# Return the size of the tuple p, which must be non-NULL and point
# to a tuple; no error checking is performed.
PyObject* PyTuple_GetItem(object p, Py_ssize_t pos) except NULL
# Return value: Borrowed reference.
# Return the object at position pos in the tuple pointed to by
# p. If pos is out of bounds, return NULL and sets an IndexError
# exception.
PyObject* PyTuple_GET_ITEM(object p, Py_ssize_t pos)
# Return value: Borrowed reference.
# Like PyTuple_GetItem(), but does no checking of its arguments.
tuple PyTuple_GetSlice(object p, Py_ssize_t low, Py_ssize_t high)
# Return value: New reference.
# Take a slice of the tuple pointed to by p from low to high and return it as a new tuple.
int PyTuple_SetItem(object p, Py_ssize_t pos, object o) except -1
# Insert a reference to object o at position pos of the tuple
# pointed to by p. Return 0 on success. Note: This function
# ``steals'' a reference to o.
void PyTuple_SET_ITEM(object p, Py_ssize_t pos, object o)
# Like PyTuple_SetItem(), but does no error checking, and should
# only be used to fill in brand new tuples. Note: This function
# ``steals'' a reference to o.
int _PyTuple_Resize(PyObject **p, Py_ssize_t newsize) except -1
# Can be used to resize a tuple. newsize will be the new length of
# the tuple. Because tuples are supposed to be immutable, this
# should only be used if there is only one reference to the
# object. Do not use this if the tuple may already be known to
# some other part of the code. The tuple will always grow or
# shrink at the end. Think of this as destroying the old tuple and
# creating a new one, only more efficiently. Returns 0 on
# success. Client code should never assume that the resulting
# value of *p will be the same as before calling this function. If
# the object referenced by *p is replaced, the original *p is
# destroyed. On failure, returns -1 and sets *p to NULL, and
# raises MemoryError or SystemError.
