I have to write a program that does the following but for some reason it doesn't work, and I'm not quite sure where the error is: Instructions :- Create modules and functions- Pass data from one function to another- Store data in lists- Create. and use selection control structures- Create. and use iterative control structures- Add comments to Python code This program creates a class registration system. It allows students to log in to add courses, drop courses and list courses they have registered for. This program has 5 functions in 2 modules: a student module and a main module. You must define the following functions in the student module.[ instructions1.png][instructions2.png]This program uses a few lists to store data. To make grading easier, data will be added to these lists at the beginning of the main function. student_list = [('1001', '111'), ('1002', '222'), ('1003', '333'), ('1004', '444')] course_list = ['CSC101', 'CSC102', 'CSC103'] max_size_list = [3, 2, 1] roster_list = [['1004', '1003'], ['1001'], ['1002']] There are 4 students in this program. ID and PIN of students are stored as tuples in student_list. The first element of each tuple is student ID, while the second element is PIN. Three courses are offered. The course codes are stored in course_list. These courses are CSC101, CSC102 and CSC103. The maximum class size of the courses offered are stored in max_size_list. The max sizes of CSC101, CSC102 and CSC103 are 3, 2 and 1, respectively. Rosters of the three classes offered are stored as three lists, which are three elements of roster_list, which is actually a list of lists. Students 1004 and 1003 are enrolled in CSC101. Student 1001 is enrolled in CSC102. Student 1002 is enrolled in CSC103. The program should have a loop to create multiple student sessions. In each session, ask user to enter ID, then call the login function to verify the student's identity. If login is successful, use a loop to allow the student to add courses, drop courses and list courses registered. The following is an example. Enter ID to log in, or 0 to quit: 1234Enter PIN: 123ID or PIN incorrect Enter ID to log in, or 0 to quit: 1001Enter PIN: 111ID and PIN verified Enter 1 to add course, 2 to drop course, 3 to list courses, 0 to exit: 1Enter course you want to add: CSC121Course not found Enter 1 to add course, 2 to drop course, 3 to list courses, 0 to exit: 1Enter course you want to add: CSC102You are already enrolled in that course.
