65. Mini Project — Student and Course Manager

1. Introduction​

Let’s apply OOP concepts (classes, attributes, methods, inheritance, encapsulation) to build a small project.

2. Requirements​

  • Manage students and courses.
  • Add/remove students.
  • Enroll students in courses.
  • Show enrollments.

3. Student Class​

class Student:
    def __init__(self, name):
        self.name = name
        self.courses = []
    def enroll(self, course):
        self.courses.append(course)

4. Course Class​

class Course:
    def __init__(self, title):
        self.title = title
        self.students = []
    def add_student(self, student):
        self.students.append(student)

5. Manager Class​

class Manager:
    def __init__(self):
        self.students = []
        self.courses = []
    def add_student(self, student):
        self.students.append(student)
    def add_course(self, course):
        self.courses.append(course)

6. Putting It Together​

s1 = Student("Alice")
s2 = Student("Bob")
c1 = Course("Math")
c2 = Course("Science")

m = Manager()
m.add_student(s1)
m.add_student(s2)
m.add_course(c1)
m.add_course(c2)

s1.enroll(c1)
s2.enroll(c2)

print(s1.name, "enrolled in", [c.title for c in s1.courses])
print(s2.name, "enrolled in", [c.title for c in s2.courses])
