interface with buttons for performing basic mathematical operations such as addition, subtraction, multiplication, division, percentage, and exponentiation.
The application is designed for desktop use and runs in a fixed-size window. All inputs are handled through the graphical interface, and calculation results are displayed directly on the screen. If an invalid expression is entered, the program shows an error message instead of crashing.
This project is mainly intended for educational purposes and is suitable for learning how to build basic graphical user interfaces (GUI) in Python using Kivy. It can also serve as a starting point for more advanced calculator or GUI-based applications.
To run the program, simply install the Kivy library and execute the Python file.
