The grading scheme for the class is:• 10% for each assignment (recall there were 4 assignments)• 20% for the midterm exam• 40% for the final examThe final grade for each student must be an integer, rounded appropriately (you can use Python's round ()function for this). The final grades should be placed into a single list and this function must return that list.Class AverageWrite a function called average () that takes a list of integers representing the grade of each student in theclass as a parameter, and returns the class average as a single, floating point number.Program OutputAt the very bottom of your program, call all of the functions you made above, using their return valuesappropriately, to print out the list containing each student's final grade, as well as the overall class average. Professor Oak is in trouble: his class grades are a mess! His midterm exam was too hard, and he gaveout too many bonus marks to certain students. For this question, you will write a program to clean up thegrades and calculate the final grade for each student in the class.Starter FileYou have been provided a starter file that contains Professor Oak's student grades as a list of lists. Eachsublist has exactly 6 items, representing the grades for (in order) four assignments, a midterm exam, anda final exam. All grades are out of 100. Just copy/paste this list to the top of your program. But keep inmind that your code should work even if we use a different starting list (though with the same format) totest your program.From here, you will write three separate functions to perform three tasks, as described below.Cleaning the DataWrite a function called clean_grades () that takes the list of lists of grades as a parameter. For all of thestudent grades, this function should perform two tasks:• Increase the midterm exam grade for ALL students by 2. Recall that the midterm grade is the 5th itemin each sublist.• For any grade greater than 100. set the grade to be just 100 (make sure to check for this AFTERincreasing the grade for the midterm exam!)These changes should be done by modifying the input list itself. No new lists should be created and thisfunction has no return value.
