Tuples are used for passing arguments to and from a function. Common

That's from Mesa, the Xerox PARC language of the 1970s.
Mesa used tuples for subroutine arguments in a very straightforward
way. Every function took one tuple as an argument, written as parameters
in parentheses separated by commas. Every function returned a tuple
as an argument. This had a nice symmetry; function outputs and
function inputs had the same form. Mesa was the first language
to break through the "single return value" syntax problem.
Python doesn't go that far.
