2.6. Tuples

Tuples are a composite data type used to store a collection of items, which are Erlang data values but which do not have to all be the same type. Tuples are delimited by curly brackets, {...}, and their elements are separated by commas. Some examples of tuples include:

{123, bcd} {123, def, abc} {abc, {def, 123}, ghi} {}
{person, 'Joe', 'Armstrong'} {person, 'Mike', 'Williams'}
