23. Tuples and dictionaries

Tuples and dictionaries are foundational data structures in Python that allow for the storage and manipulation of multiple values. Tuples are immutable sequences, while dictionaries provide a flexible way to associate keys with values using more complex types, such as strings. Understanding these structures enhances a programmer's ability to handle data efficiently in Python applications.
