Python Calculator Tutorial
In this tutorial, you’ll learn how to create a fully functional calculator using Python’s Tkinter library.

We’ll guide you through designing a sleek GUI (graphical user interface) for the calculator, styling the buttons to mimic an iPhone calculator, updating a display label with input numbers, and performing different mathematical operations using button clicks.

button_values = [
["AC", "+/-", "%", "÷"],
["7", "8", "9", "×"],
["4", "5", "6", "-"],
["1", "2", "3", "+"],
["0", ".", "√", "="]
]

right_symbols = ["÷", "×", "-", "+", "="]
top_symbols = ["AC", "+/-", "%"]
root_symbols = ["√"]
