Student Management System (SMS) – Python Project

Hi! My name is Samra and this is my Python project for a basic Student Management System. I made this to practice some important Python concepts like classes (OOP), file reading/writing, creating my own Python package, and also using iterators and generators.

This project helped me understand how a simple system can manage student data like name, ID, courses, grades, attendance, etc.

Project Files (What’s Inside)?

1. SMS.py

In this file, I created two classes:

  • Student → for storing details like name, age, student ID, and courses.
  • GraduateStudent → a child class that also includes thesis title.

I also added a method to calculate GPA from a list of grades. At the end, I created one student and tested everything to make sure it works.

2. file_handling.py

This file helps with saving and reading student records from a text file.

I wrote two main functions:

  • write_students() → saves student info to a file.
  • read_students() → reads data back and shows it on screen.

I also added error messages in case the file is missing or something goes wrong.

3. student_utils/ (My Own Python Package!)

Here I made a custom Python package with three simple modules:

  • arithmetic.py → calculates percentage and assigns grades.
  • attendance.py → finds attendance percentage.
  • performance.py → tells if a student is doing "Excellent", "Good", or "Needs Improvement" based on GPA.

There’s also a main.py file that uses all these functions to check if they’re working.

4. iterators_generators.py

In this file, I practiced:

  • Iterator → to go through a list of students one by one.
  • Generator 1 → to randomly mark students as "Present" or "Absent".
  • Generator 2 → to give random marks (just for testing).

It was fun trying these things out and now I understand how iterators and generators work!

What I Learned

  • How to write Python classes using OOP and inheritance.
  • How to read and write from files safely.
  • How to make my own Python package with multiple modules.
  • What iterators and generators are, and how to use them in real situations.

Notes

I kept every file simple and added some comments to explain what’s happening.

Also, I tested each file using this condition:

if __name__ == "__main__":

So that I could run each one separately and check if it works fine.

Thanks for checking my project!
