Sets and tuples
A tuple is an immutable list written with parentheses `()`. A set is an unordered collection of unique elements written with curly braces `{}`.
How it reads
point = (10, 20) defines an immutable tuple
{"wispy", "puffy", "wispy"} creates a set, filtering out duplicates
Cloud tip: Use sets when checking membership or removing duplicates, and tuples for structured coordinates or records.
