TUPLE

Etymology

Noun

tuple (plural tuples)

(set theory) A finite sequence of terms.

A tuple is not merely a totally-ordered set because the same element can appear more than once in a tuple: for example, \((a, b, a)\) qualifies as a 3-tuple whereas it would not qualify as a totally-ordered set (of cardinality 3), because the set would be \(\{a, b\}\) where \(a \le b \) and \(b \le a\) so that \(a = b\); i.e, it would actually be a one-element set, \(\{a\}\), not even just two-element.

(computing) A single row in a relational database.

(computing) A set of comma-separated values passed to a program or operating system as a parameter to a function call.

(computing) In some programming languages, a data type that is similar but distinct from the list data type, whose instances are characterized by having a rather fixed arity, and the elements of which instances can differ from each other by data type. (Note: this definition may overlap with the previous one.)

Synonyms

• (finite sequence of terms): n-tuple (when the sequence contains n terms), ordered pair (when the sequence contains exactly two terms), triple or triplet (when the sequence contains exactly three terms)

Anagrams

• let up, let-up, letup, plute
