A dictionary is a collection that is unordered, changeable, and indexed. In Python, dictionaries are written with curly brackets, and they have keys and values.

You can access the items of a dictionary by referring to its key name, inside square brackets.

Dictionaries are optimized to retrieve values when the key is known.
