tuple_lengthtuple_lengthTupleLengthTupleLengthtuple_length (Operator)

tuple_lengthtuple_lengthTupleLengthTupleLengthtuple_length — Return the number of elements of a tuple.

Signature

tuple_length( : : Tuple : Length)

Herror tuple_length(const Hlong Tuple, Hlong* Length)

Herror T_tuple_length(const Htuple Tuple, Htuple* Length)

void TupleLength(const HTuple& Tuple, HTuple* Length)

HTuple HTuple::TupleLength() const

static void HOperatorSet.TupleLength(HTuple tuple, out HTuple length)

HTuple HTuple.TupleLength()

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

Description

tuple_lengthtuple_lengthTupleLengthTupleLengthtuple_length returns the number of elements of the input tuple TupleTupleTupletupletuple.

Exception: Empty input tuple

If the input tuple is empty, the operator returns 0.

HDevelop In-line Operation

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

Length := |Tuple|

Execution Information

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