The term "Tuple" refers to a bound set of values, in a given order. This has implications in math and computer science. Many programming languages include special handling for Tuple data types.

Distinction from "Sequence" in Math

• Tuples are finite, sequences aren't always
• Sequences always have the same type of elements, a Tuple could include a number, a matrix, and some sort of formula

Distinction from "List" in Python

• Tuples are immutable, lists may be changed after they are declared

Examples

• (4, 8, 15, 16, 23, 42)
• (4, "eight", 15, 16, "twenty three", 42)
• A distinct set of (x, y, z) as an input to a given function: f(x, y, z)
• In relational databases, the contents of a row are a Tuple
