CIS 110 Python Project Help & Programming Assignment

Executive Summary

The Student Grade Management System is a comprehensive Python application designed to manage student records, course information, and grade tracking. This CIS 110 project demonstrates proficiency in object-oriented programming, file I/O operations, and user interface design. The system allows administrators to add students, manage courses, record grades, and generate performance reports with automatic GPA calculation.

Project Architecture & Design Patterns

The application uses object-oriented design with three main classes working together to manage the complete grade tracking system:

• Student Class: Manages individual student data including ID, name, email, major, and enrolled courses with validation
• Course Class: Handles course information including code, name, credits, instructor, and enrolled students
• GradeBook Class: Maintains grade records and calculates GPA, course averages, and performance metrics

Core Features Implemented

Student Management Module:

• Add new students with validation (name, ID, email format checking)
• Update student information and course enrollment
• Delete student records with confirmation prompts
• Search students by ID, name, or major
• Display all students with formatted output

Course Management System

Course Operations:

• Create new courses with course code, name, and credit hours
• Enroll students in courses with capacity management
• Remove students from courses
• View all enrolled students for each course
• Track course capacity and enrollment limits

Grade Recording & Calculation

Grade Processing Features:

• Input grades with automatic validation (0-100 range)
• Automatic GPA computation using weighted grade calculation
• Letter grade assignment (A, B, C, D, F) based on numerical scores
• Course average calculation for all students
• Performance reports showing top performers and struggling students

File I/O Operations & Data Persistence

File Management Features:

• Save student records to CSV files for data persistence
• Load student data from files on program startup
• Export grade reports to formatted text files
• Error handling for file operations with try-except blocks
• Automatic backup creation before data modifications

Error Handling & Input Validation

Robust Exception Management:

• Input validation for all user entries (name, ID, grades)
• Try-except blocks for file operations and data processing
• Custom error messages for invalid inputs
• Duplicate ID prevention with set data structures
• Grade range validation (0-100) with user prompts

User Interface & Menu System

Command-Line Interface Design:

• Main menu with 8+ options for different operations
• Submenu navigation for student and course management
• Formatted output tables for displaying student and course data
• Clear prompts and instructions for user guidance
• Exit confirmation to prevent accidental program termination

Code Structure & Best Practices

Programming Standards Demonstrated:

• Modular design with 15+ custom functions for different tasks
• Proper use of docstrings and comments throughout code
• DRY (Don't Repeat Yourself) principle with reusable functions
• Consistent naming conventions for variables and functions
• Proper indentation and code formatting following PEP 8
