Capstone Project 2: Student Report Card Generator in Python

In this final capstone project of the intermediate curriculum, we unite all major technical competencies acquired across this course—Data Structures, File Handling with JSON & CSV, Object-Oriented Design, Exception Safety, Statistical Metrics, and Visual Chart Generation with Matplotlib—to build an automated Academic Report Card & Performance Analytics Generator.

1. System Architecture & Objectives

Our system automates academic transcript generation for schools and universities:

1
Data Ingestion: Parses student profiles, subjects, and examination marks from structured JSON or CSV datasets.
2
Academic Analytics Engine:

Computes Total Marks, Percentage, Weighted GPA (on a 10.0 scale), and Letter Grades (A+, A, B, C, F).
Calculates Class Averages per subject for benchmark comparison.

1
Multi-Format Publishing:

Generates a formatted ASCII/Text Official Academic Transcript.
Generates a visual performance comparison chart (report_card_<roll_no>.png) plotting individual student scores alongside the class average using Matplotlib.

⚠️ Common Intermediate Mistakes & Gotchas

1. Accumulating Figure Buffers Across Multiple Students

Always call plt.close(fig) after exporting each student's PNG chart to prevent memory exhaustion when generating report cards for large classrooms.

2. Hardcoded Directory Paths

Ensure the output directory is created safely using os.makedirs(output_dir, exist_ok=True) before saving report cards and chart images.

💻 Try It Yourself: Extension Challenge - Rank Calculation

Challenge

Extend the Report Card Generator to compute and display each student's class rank based on their cumulative GPA.

Complete Solution

1def calculate_class_ranks(students_data):
2    # Sort students descending by GPA
3    ranked = sorted(students_data, key=lambda s: s["gpa"], reverse=True)
4    for rank, student in enumerate(ranked, 1):
5        student["rank"] = rank
6    return ranked

11    {"name": "Kavya", "gpa": 8.6}
12]
13 
14for s in calculate_class_ranks(cohort):
15    print(f"Rank #{s['rank']}: {s['name']} (GPA: {s['gpa']})")

Expected Output

1Rank #1: Diya (GPA: 9.4)
2Rank #2: Aarav (GPA: 8.9)
3Rank #3: Kavya (GPA: 8.6)
