Description of the Problem In this assignment, you are required to a new grading system which, includes the menu system to allow the lecturer to input the students' marks for different subjects. The system is able to calculate the grade and CGPA for the students. Store and persist the students' details in the file (students.txt) for further processing. Retrieve the student records from the file whenever the user wants to manipulate the student records such as adding an additional new subject and mark to the system. You have to use the list or dictionary or both in storing the student records in the memory. The student file structure is shown as follows: [Student Id],[Name]. [Subject! Mark], [Subject2 Mark], [Subject3 Mark] Example S20001, Ow Yi Han, CSC1101 86, csc1102 75, csc1103 60 The above example illustrates that the student id is S20001 with the name "Peter" and has three subjects (CSC1101, CSC1102, csc1103) with different marks.
