Python provides another composite data type called a dictionary, which is similar to a list in that it is a collection of objects. Here’s what you’ll learn in this tutorial: You’ll cover the basic characteristics of Python dictionaries and learn how to access and manage dictionary data.

A Python dictionary is a collection of items, similar to lists and tuples. However, unlike lists and tuples, each item in a dictionary is a key-value pair (consisting of a key and a value).

A Python dictionary is a collection of key-value pairs where each key is associated with a value. A value in the key-value pair can be a number, a string, a list, a tuple, or even another dictionary. In fact, you can use a value of any valid type in Python as the value in the key-value pair. A key in the key-value pair must be immutable.
