Intuit Build Challenge

This repository contains my submission for the Intuit Build Challenge, consisting of two independent tasks implemented in Python.

---

Task 1 – Library Management System

A simple object-oriented library system that supports:

• Adding books and registering members
• Checking out and returning books
• Enforcing borrowing limits and fine rules
• Calculating overdue fines
• Tracking borrowing history
• Unit testing core functionality

Details: See Task1/README.md for full documentation, assumptions, and usage instructions.

---

Task 2 – Order Invoice Summary

A file-processing application that:

• Parses pipe-delimited order records from a text file
• Applies business rules and discounts
• Aggregates data by customer
• Generates a formatted invoice summary report
• Logs malformed or invalid records
• Includes unit tests for validation and edge cases

Details: See Task2/README.md for full documentation, assumptions, and usage instructions.

Setup

Each task is self-contained and includes its own requirements.txt.

To run a task:

1. Navigate to the task directory
2. Create and activate a virtual environment
3. Install dependencies
4. Run the program or tests as described in the task README

---

Testing

Both tasks use pytest for unit testing.

Tests are designed to:

• Cover core functionality
• Validate business rules
• Handle edge cases and invalid inputs
• Ensure deterministic behavior

---

Notes

• All design assumptions are explicitly documented in the respective task README files

Thank you for reviewing my submission.
