Developed a comprehensive desktop application combining a Library Management System with a Car Loan Calculator. The library system uses object-oriented programming principles with inheritance between physical books and eBooks, while the loan calculator provides a graphical interface for calculating car loan payments with validation and user feedback.
Manage both physical books and eBooks with a class hierarchy using inheritance
Calculate car loan payments with interest rates based on loan duration
User-friendly interface built with Tkinter for car loan systems
Comprehensive validation for all user inputs with error handling
One of the main challenges was implementing the inheritance structure between physical books and eBooks while maintaining a consistent interface. This was solved by creating a base Book class with common attributes and methods, then extending it for specific book types.
Another challenge was designing an intuitive user interface for car loan calculator. The Tkinter loan calculator functionalities, with appropriate validation and user feedback mechanisms.
