As we approach the conclusion of Python data structures, we’ll examine the tuple. Used less frequently than lists and dictionaries, tuples do serve some handy use cases where immutability is a critical requirement.

Both lists and dictionaries can retain structured data in Python. The dictionary is unique in that it stores individual…

Both lists and dictionaries can retain structured data in Python. The dictionary is unique in that it stores individual entries with human-readable logical names rather than index numbers.
