I developed a comprehensive calculator application using Python's Tkinter library and object-oriented programming techniques. The application features four main functions: a basic calculator, a scientific calculator, a currency converter using real-time exchange rates from the ExchangeRate API, and a temperature converter. The user interface is intuitive and easy to use, allowing users to quickly and easily access the various calculator functions. This project demonstrates my ability to design and implement complex software solutions using a variety of programming concepts and tools in Python.
