Tuple
1) In programming languages, such as LISP, Python, Linda, and others,
a tuple (pronounced TUH-pul) is an ordered set of values. The
separator for each value is often a comma (depending on the rules of
the particular language). Common uses for the tuple as a data type
are (1) for passing a string of parameters from one program to
another, and (2) representing a set of value attributes in a
relational database. In some languages, tuples can be nested within
other tuples within parentheses or brackets or other delimiters.
Tuples can contain a mixture of other data types.
Here's an example of a tuple that emphasizes the different data types
that may exist within a tuple data type:
17,*,2.49,Seven
The above example is sometimes referred to as a 4-tuple, since it
contains four values. An n-tuple would be one with an indeterminate
or unspecified number of values.
2) A tuple is analogous to a record in nonrelational databases.
The term originated as an abstraction of the sequence: single,
double, triple, quadruple, quintuple, ... n-tuple. Tuple is used in
abstract mathematics to denote a multidimensional coordinate system.
