This is a basic four-function calculator that I made solely with Python! It's very basic and just uses defined functions to calculate the
operations. While working on this, I struggled with the "power on" and "power off" mechanisms of the calculator, often having a permanently
"on" calculator. In the process, however, I learned how to better manage the True boolean in a while loop, as well as how to import
custom functions from another Python file.
In the future, I hope to update the calculator to include (i) a longer input section so that more than just two numbers can be used in calculations, (ii) more functions beyond just the basic four functions (e.g., trigonometric functions, integration, derivation, etc.), and (iii) a better interface with interactive buttons. Essentially, I want to replicate the TI-Nspire CX I and II CAS's digital software that's used on computers without the calculator.
