A tuple is a sequence of immutable Python objects. Tuples are sequences, just like lists. A tuple is a collection that is ordered and unchangeable. In Python, tuples are written with round brackets.

Python lists significantly impact code optimization. It offer versatility and efficiency for storing and manipulating data, allowing for quick access, insertion, and removal of elements.

Tuple. Consider this starfish. It has 5 arms. It is underwater. These attributes form a unit of information—they could be stored together in a tuple. Python tuples are values—they never change.
