Continuing with the previous scenario, a student eligible for admission has to choose a course and pay the fees for it. If they have scored more than 85 marks in qualifying exam, they get 25% discount on fees.
Valid course ids and fees are given below:
course id | fees |
|---|---|
1001 | 25575.0 |
1002 | 15500.0 |
Extend the program written in the previous assignment to include the above requirement.
Instance variables and methods to be included in Student class are given below.
Class name: Student
Attributes | course_id |
|
Methods | __init__() | Create and initialize newly created instance variables also to None |
| choose_course(course_id) | Accept the course_id chosen by the student.
|
| getter methods | Include getter methods for newly added instance variables |
