Student Management System

Overview

The Student Management System is a simple application built using Object-Oriented Programming (OOP) principles in Python. This system allows for the management of students, instructors, courses, and enrollments. The project demonstrates the use of classes, objects, inheritance, polymorphism, and encapsulation.

• Enroll Students: Enroll students in courses.
