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.

given dictionaries, d1 and d2, create a new dictionary with the following property. For each entry(a,b) in d1, if a is not a key of d2 then add (a,b) to the new dictionary. For each entry (a,b) in d2, if a is not a key of d1 then add (a,b) to the new dictionary. For example, if d1 is {2:3, 8:19, 6:4, 5:12} and d2 is {2:5, 4:3, 3:9}, then the new dictionary should be {8:19, 6,4, 5:12, 4:3, 3:9}. using puthon

All course code will have 3 digits with the department name of 3 letters. Any course code not following this rule is Invalid. Write a python program that creates a dictionary from the above list where the keys will be each department name (CSE,EEE,MAT for the above example) or Invalid. Departments will contain a list of valid courses for that department. Sample Input - No need to take input ['CSE110','CSE111','MAT620','CS520','EEE361','CSE650','MAT5100','CSEE21','MAT3210'] Sample Output : (You just need to print the resultatnt dictionary.
