in python what is the answer

Exercise 3 Actually, not all courses have the same weight: the weight depends on the credit value. Modify the previous code to request the credit value of each course and compute the weighted average: the weighted average represents the sum of the grades multiplied by their credit value divided by the sum of all grades. Here is a sample run: Enter the number of courses that you are taking this semester: 4 Enter the course code for course \#1: COMM1020 Enter the number of credits of COMM1020: 3 Enter the grade obtained in Comm1020: 92 Enter the course code for course \#2: INFS1201 Enter the number of credits of INFS1201: 4 Enter the grade obtained in INFS1201: 78 Enter the course code for course \#3: INFT1201 Enter the number of credits of INFT1201: 4 Enter the grade obtained in INFT1201: 96 Enter the course code for course \#4: MATH1030 Enter the number of credits of MATH1030: 3 Enter the grade obtained in MATH1030: 86 Your average for this semester is: 87.8571428571
