tuple_last_ntuple_last_nTupleLastNTupleLastNtuple_last_n (Operator)

tuple_last_ntuple_last_nTupleLastNTupleLastNtuple_last_n — Select all elements from index “n” to the end of a tuple.

Signature

tuple_last_n( : : Tuple, Index : Selected)

Herror tuple_last_n(const Hlong Tuple, const Hlong Index, Hlong* Selected)

Herror T_tuple_last_n(const Htuple Tuple, const Htuple Index, Htuple* Selected)

void TupleLastN(const HTuple& Tuple, const HTuple& Index, HTuple* Selected)

HTuple HTuple::TupleLastN(const HTuple& Index) const

static void HOperatorSet.TupleLastN(HTuple tuple, HTuple index, out HTuple selected)

HTuple HTuple.TupleLastN(HTuple index)

def tuple_last_n(tuple: MaybeSequence[Union[float, int, str]], index: int) -> Sequence[Union[float, int, str]]

def tuple_last_n_s(tuple: MaybeSequence[Union[float, int, str]], index: int) -> Union[float, int, str]

Description

Starting with the “n-th” element of the tuple TupleTupleTupletupletuple, tuple_last_ntuple_last_nTupleLastNTupleLastNtuple_last_n selects every element of TupleTupleTupletupletuple and returns it with SelectedSelectedSelectedselectedselected. Thus, SelectedSelectedSelectedselectedselected contains all elements of TupleTupleTupletupletuple from index “n” up to the last element of TupleTupleTupletupletuple (including the element at position “n”). The index “n” is determined by the input parameter IndexIndexIndexindexindex. Thus, IndexIndexIndexindexindex must contain a single integer value (if IndexIndexIndexindexindex consists of a floating point number, this must represent an integer value without fraction). Indices of tuple elements start at 0, that means, the first tuple element has got the index 0.

Exception: Empty input tuple

If TupleTupleTupletupletuple is empty, an exception is raised.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_last_ntuple_last_nTupleLastNTupleLastNtuple_last_n, which can be used in an expression in the following syntax:

Selected := lastn(Tuple, Index)

Execution Information

• Multithreading type: independent (runs in parallel even with exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
