Question
Create a Python program for Professor P.
Create a class named Student that holds the following data about a student:
1. Name
2. Student ID number
3. GPA
4. Expected grade in this course
5. Full time or part time
Create five student objects from this class and pass data to fill in the class data above.
Besides creating the objects, you will write a menu-driven program that performs the following tasks:
1. Look up and print the student GPA
2. Add a new student to the class
3. Change the GPA of a student
4. Change the expected grade of a student
5. Print the data of all the students in a tabular format
6. Quit the program
