In most universities, course grades are reported using a letter grade, i.e. A, B, ..., whereas the overall performance is reported using Grade Point Average (GPA). First, a number (typically in the range from 0 to 4) is assigned to each letter grade. The GPA is calculated by summing the weighted grade points (credit hours * numerical value of the grades) then dividing by the total amount of credit hours. So, for example suppose, consider the simplified grade scale that assigns letter grades of 'A', 'B', 'C', 'D', and "F", to grade points '4', '3', '2', '1', and '0', respectively. If your grades for Biology (3 credits), Math (4 credits). Computer Science (3 credits), and Physics (2 credits) are 'BBAD, then you GPA will be calculated as (rounded to a decimal digit) (3*3) + (43)+(3*4)+(2+1) 3+4+3+2 (a) Write a Python user-defined function that calculates the GPA on a scale of 0 to 4, as above. That is A = 4, B = 3, C = 2, D = 1, and F = 0. Your function should take two input vectors, 'Grades" containing the letter grades and 'Hours' containing the credit hours for each course in 'Grades'. It should output the GPA. Hint: You can consider using the following Python commands: sum, len, and if-elif-else. GPA 2.9 (b) Suppose your grades for a term are as stated in the example above. That is they are ['B', 'B', 'A', 'D'] for Biology (3 credits), Math (4 credits), Computer Science (3 credits), and Physics (2 credits). Your program should create two lists, one for the grades and one for their corresponding hours. It should then use your user-defined function from part (a) to calculate and display the resulting GPA. Important: You have to do this problem in Python. You will not receive any credit if you do this problem in Matlab. In your report, include your Python .py script file that should include your function file (with sufficient comments).
