Interactive Class Management System (Python Dictionary-Based Program)

On February 24, 2026, at the University of Blida, Saad Dahlab, Department of Process Engineering, Industrial Pharmacy section, Master 1, our practical and tutorial instructor for the module "Elements of Applied AI" asked us to solve exercise number 3 from the exercise series entitled "Lab1: Lists & Dictionary (Introduction to AI)" to make a small project.The file I shared is the Python code for the exercice. Program descreption : This exercise is about creating a simple class management system in Python using a dictionary and lists. Each student’s name is stored as a key in a dictionary, and their grades are stored as a list associated with that key. The program allows the user to display all students and their grades, search for a specific student, calculate average grades, add a new student with their grades, and add new grades to existing students. The objective is to practice working with dictionaries and lists together, accessing and modifying nested data, using loops and conditions, and performing basic calculations like averages.
