- What are the advantages of using a dictionary data structure?Assume a dictionary with some values: students = { 'CCU101': ['Anna', 88.5, 98.5, 78, 85, 92.5], ' CCU102': ['Alex', 98,91,90,92,88], 'CCU103': ['Bob', 99.5, 98.5, 96, 96, 89.5], } To access, a specific row, you would use students[key][column_number]. students['CCU101'][0] would print 'Anna' students['CCU101'][1] would print 88.5 and so on.. Write a program that defines a function that takes a dict as an argument, adds the scores of each student, calculate average for each student, and display them. Define a function display_average(students) that takes in a dictionary as an argument. Display the original dictionary. Calculate and display the average of each student. You do not need to ask user for input. You can use your own dictionary with at-least 5 rows.Explain the concept of a dictionary in computer science.
