tuple_lesstuple_lessTupleLessTupleLesstuple_less (Operator)
Name
tuple_lesstuple_lessTupleLessTupleLesstuple_less — Test whether a tuple is less than another tuple.
Signature
Herror tuple_less(const Hlong T1, const Hlong T2, Hlong* Less)
Herror T_tuple_less(const Htuple T1, const Htuple T2, Htuple* Less)
void TupleLess(const HTuple& T1, const HTuple& T2, HTuple* Less)
HTuple HTuple::TupleLess(const HTuple& T2) const
def tuple_less(t1: MaybeSequence[Union[int, float, str]], t2: MaybeSequence[Union[int, float, str]]) -> int
Description
tuple_lesstuple_lessTupleLessTupleLesstuple_less tests whether the input tuple T1T1T1t1t1 is less
than T2T2T2t2t2. A tuple T1T1T1t1t1 is said to be less than a
tuple T2T2T2t2t2, if T1T1T1t1t1 has been found to be less when
comparing it elementwise to T2T2T2t2t2 or if the first
min(|T1|,|T2|) elements are equal and T1T1T1t1t1 has got less
elements than T2T2T2t2t2.
With the elementwise comparison, the elements of T1T1T1t1t1 and
T2T2T2t2t2 are compared one by one. If the two elements are equal,
the next pair of elements will be examined. If the element of
T1T1T1t1t1 is less than that from T2T2T2t2t2, the result is 1 and
the comparison will be aborted. If the element of T1T1T1t1t1 is
greater than that from T2T2T2t2t2, the result is 0 and the comparison
will be aborted. If all elements have been tested and if all were
equal, the result is 0.
As a precondition for comparing the tuples elementwise two
corresponding elements must either both be (integer or floating point)
numbers or both be strings. Otherwise tuple_lesstuple_lessTupleLessTupleLesstuple_less returns an
error.
Exception: Empty input tuples
If one input tuple is empty and the other is not, the tuple that is
empty is considered less than the one that is not empty.
