Indexing and slicing tuples
When to use tuples (returning multiple values, dictionary keys)
Tuple unpacking basics
namedtuple (brief introduction)

Learning Objectives

Create tuples using parentheses and the tuple() constructor
Explain how immutability affects tuple usage
Index and slice tuples like lists
Choose tuples over lists for appropriate use cases
