Answer:A tuple (pronounced TUH-pul) is a data structure in some programming languages that is an ordered list of elements.
A tuple may include zero or more elements. To indicate how many elements it contains, it may be referred to as an n-tuple, where "n" is the number of elements.
Often, a tuple is represented as a comma-delimited list of the elements, enclosed in parentheses. For example, "(5, 9, 11, 3, 22, 14)" is a "6-tuple."
Benefits and limitations of a tuple
Tuples are usually immutable, that is, their elements cannot be modified or deleted after they are set. Tuples are usually more performant (their data may be accessed faster) than a regular list. A tuple is an ideal data structure for a list of heterogenous items (that differ in type or length) whose value does not change.
