In mathematics, a tuple is a finite ordered list of elements. An n-tuple is a sequence of n elements, where n is a non-negative integer. There is only one 0-tuple, referred to as the empty tuple. An n-tuple is defined inductively using the construction of an ordered pair. What are tuples used for? Tuples are used to group together related data, such as a person\’s name, their age, and their gender. An assignment to all of the elements in a tuple using a single assignment statement. Tuple assignment occurs simultaneously rather than in sequence, making it useful for swapping values.
