I Built a Student Grade Book
Web App from Scratch 🎓
A full-stack education platform with Python analytics, real-time web dashboard, live rankings — built from zero. No frameworks. No shortcuts.
👋 What I Built & Why
As part of my journey at Masai School and my training program at Infosys, I was given a challenge: build a Student Grade Book using Python data structures. Instead of stopping at the basic requirement, I went further and built a complete full-stack platform with two versions:
Python CLI Dashboard
291-line terminal app with ASCII progress bars, subject analytics, search, rankings, dynamic add — runs anywhere Python is installed
Web Dashboard
Dark luxury UI — real-time charts, search & filter, edit modal, CSV export, mobile responsive — all in one single HTML file
Live Analytics
Class average, pass rate, subject-wise breakdowns, grade distribution — all update instantly when you add or edit students
Rankings System
🥇🥈🥉 live leaderboard, top student spotlight with gold banner, sortable table — like a real school management system
✨ All Features
🧠 Python — All 4 Data Structures
This project uses all 4 Python data structures meaningfully — not just to tick a box:
students = ['Raj', 'Priya', 'Amit', 'Sneha', 'Karan']
print(students[:3]) # → ['Raj', 'Priya', 'Amit']
# ─── TUPLE — immutable (subjects never change) ────────────
subjects = ('Math', 'Science', 'English')
# ─── DICTIONARY — key-value mark storage ──────────────────
marks = {
'Sneha': {'Math': 95, 'Science': 90, 'English': 92},
'Priya': {'Math': 92, 'Science': 88, 'English': 85},
'Raj' : {'Math': 85, 'Science': 78, 'English': 90},
}
# ─── SET — unique grades, zero duplicates ─────────────────
unique_grades = set() # Even if 'A' added 10 times → stored once
# ─── Lambda + max() — find top student ────────────────────
top = max(students, key=lambda s: sum(marks[s].values()) / 3)
print(f"Top Student: {top}") # → Sneha

🏆 Final Class Rankings
🗺️ How It Works
Data Input
Student names stored in a List, marks in a Dictionary, subjects in a Tuple — structured like a real database
Calculate Average
sum(scores.values()) / 3 for each student — clean, readable Python
Assign Grade
≥85 → A · ≥70 → B · <70 → C — stored in a Set for unique tracking
Find Top Student
max() + lambda sorts all students by average — Sneha wins with 92.33
Output
Python CLI → beautiful ASCII terminal dashboard · Web → dark luxury real-time UI
