What is a List in Python?

A list is a data structure in Python that is an ordered sequence of mutable elements. A list's elements are referred to as items. Lists are composed of values separated by commas and enclosed in square brackets ([]).

A list is an excellent tool for dealing with related values. Because lists can be changed, you can add, update, or delete items while programming at any time. For example, consider the code as:

x_list = ["BYJUS", "Exam", "Prep"]

print(x_list)

Output:

["BYJUS", "Exam", "Prep"]

What is a Dictionary in Python?

Python includes a data structure called a dictionary. It is used to store a collection of key-value pairs of data. A dictionary was previously an unordered collection, but the order is somewhat preserved in Python 3.6.

Dictionary entries are written inside curly brackets, separated by commas. On the other hand, the data's key and value are separated by a semicolon (:). Dictionary elements are arranged in a specific order, and can be changed but cannot be duplicated.
