Dictionary and its methods in Python

What is a Python dictionary?
This is generally a data structure that stores data items in key-value pairs. What does it mean when we talk about key and value? A key uniquely identifies an element, while a value corresponds to the data or element associated with the key. Dictionaries store large amounts of information, such as words and even the names of students in a class. They can be modified after creation and may contain unordered lists.
