Tuple
In mathematics, a tuple is a finite sequence of objects. Sometimes, the finite sequence is also called an ordered list. This means that the order of the objects matter. In a tuple, the objects are either enclosed within parentheses (such as [math]\displaystyle{ (1, 2) }[/math]),[1] or within angle brackets (such as [math]\displaystyle{ \langle 1, 2 \rangle }[/math]).[2] Each of the objects in the list has a certain type. A tuple consisting of n entries is called an n-tuple.[3] Tuples are used to describe mathematical objects that are made of certain, well-defined components. They are also used very frequently with databases. Tuples are different from sets:
- A certain element can be in a tuple more than once.
- The order in which the elements appear in a tuple is important.
In other words, tuples are like ordered multisets.
