Code:

import tkinter as tk
from tkinter import messagebox

Create the main window
root = tk.Tk()
root.title("Simple Calculator")
root.geometry("500x500")

Global variable for storing the expression
expression = ""

Function to update the expression in the entry widget
def press(num):
global expression
expression += str(num)
equation.set(expression)

Function to evaluate the final expression
def equalpress():
try:
global expression
total = str(eval(expression))
equation.set(total)
expression = total
except:
equation.set("Error")
expression = ""

Function to clear the expression in the entry widget
def clear():
global expression
expression = ""
equation.set("")

Entry field for showing expression/result
equation = tk.StringVar()
expression_field = tk.Entry(root, textvariable=equation, font=("Arial", 20), bd=10, insertwidth=4, width=25, borderwidth=4)
expression_field.grid(row=0, column=0, columnspan=4)

Button layout
buttons = [
('7', 1, 0), ('8', 1, 1), ('9', 1, 2), ('+', 1, 3),
('4', 2, 0), ('5', 2, 1), ('6', 2, 2), ('-', 2, 3),
('1', 3, 0), ('2', 3, 1), ('3', 3, 2), ('*', 3, 3),
('C', 4, 0), ('0', 4, 1), ('=', 4, 2), ('/', 4, 3),
]

Create buttons using a loop
for (text, row, col) in buttons:
if text == '=':
btn = tk.Button(root, text=text, height=3, width=8, font=("Arial", 18), command=equalpress)
elif text == 'C':
btn = tk.Button(root, text=text, height=3, width=8, font=("Arial", 18), command=clear)
else:
btn = tk.Button(root, text=text, height=3, width=8, font=("Arial", 18), command=lambda txt=text: press(txt))
btn.grid(row=row, column=col)

Start the GUI loop
root.mainloop()
