What is the difference between a dictionary and a dictionary view in Python?

A dictionary in Python is a collection of key-value pairs, where each key is unique. A dictionary view is an object that provides a dynamic view on the entries of a dictionary. There are three types of dictionary views: **keys**, **values**, and **items**, which represent the keys, values, and key-value pairs of the dictionary, respectively.

The main difference between a dictionary and a dictionary view is that a dictionary view is dynamic, meaning it changes as the underlying dictionary changes. For example, if you add or remove an entry from the dictionary, the corresponding view will change as well. On the other hand, dictionaries are static and do not change with the dictionary. Additionally, dictionary views are read-only, so you cannot modify the entries of the view, only the underlying dictionary.
