Dictionaries

As you have learned, a set is a collection of distinct elements (non-repeated elements). A dictionary is used to store [key, value] pairs, where the key is used to find a particular element.

In this chapter, we will cover some examples of the use of the dictionary data structure in the real world: a dictionary itself (the words and their definitions), and an address book.
