create a python calculator app #2
Description
Prompt:
Create a Python program that implements a simple calculator with a graphical user interface (GUI). The calculator should support basic arithmetic operations (addition, subtraction, multiplication, and division). Use a standard Python GUI library such as Tkinter or PyQt. The interface should include:
A display area to show the current input and result
Buttons for digits (0–9)
Buttons for basic operations (+, -, ×, ÷)
A button to clear the input
A button to calculate the result (=)
Make sure the program runs as a standalone script and opens a working calculator window when executed.
