Create a program that reads strings of student grades records and calculates their corresponding letter grade. Name file Your Name_Assignment_4_letter_grade.py The program reads strings of the form: "lastName, firstName, grade1, grade2, grade3, grade 4" For example: "Baker, Alice, 23, 24, 25, 24" The program shall add the grades, and assign a letter grade based on the following criteria: - 'A' if the sum of the grades is 90 or more, - 'B' if the sum of the grades is between 80 and 89, - 'C' if the sum of the grades is between 70 and 79, - 'D' if the sum of the grades is between 60 and 69, - 'F' if the sum of the grades is 59 or less. The output of the program shall have the form: "firstName lastName letterGrade" Here is a sample run of the program: Enter student grades record: Baker, Alice, 23, 25, 25, 24 Result: Alice Baker A Hint: Use the split method to convert the input string into a list. Make sure the list has exactly 6 items; otherwise, end the program with an error message. Convert the grades (the last four items in the list) to integer values. Use the sum function to add the grades, which we can access using the slicing operator. Determine the corresponding letter grade based on the criteria in the exercise, and produce the required output, knowing that the last name is at position 0, and the first name is at position 1 of the list Step by Step Solution
