Chapter 12. Tuples

This chapter presents one more built-in type, the tuple, and then shows how lists,
dictionaries, and tuples work together. I also present a useful feature for variable-length
argument lists: the gather and scatter operators.

One note: there is no consensus on how to pronounce “tuple”. Some people say “tuh-ple”,
which rhymes with “supple”. But in the context of programming, most people say “too-
ple”, which rhymes with “quadruple”.
