CREATE SIMPLE CALCULATOR

                                              CREATE SIMPLE CALCULATOR 

  

Certainly! Here's an example of a simple calculator GUI (Graphical User Interface) application using the `tkinter` library in Python:

```python

import tkinter as tk

def btn_click(event):

    text = event.widget.cget("text")

    

    if text == "=":

        try:

            result = str(eval(screen.get()))

            screen.set(result)

        except Exception as e:

            screen.set("Error")

    elif text == "C":

        screen.set("")

    else:

        screen.set(screen.get() + text)

root = tk.Tk()

root.geometry("400x600")

root.title("Calculator")

screen = tk.StringVar()

screen.set("")

entry = tk.Entry(root, textvar=screen, font="Arial 30 bold", justify="right")

entry.pack(fill=tk.BOTH, ipadx=8, padx=10, pady=10)

buttons = [

    ("7", "8", "9", "/"),

    ("4", "5", "6", "*"),

    ("1", "2", "3", "-"),

    ("0", ".", "=", "+"),

    ("C")

]

for button_row in buttons:

    frame = tk.Frame(root)

    frame.pack(fill=tk.BOTH)

    for button_text in button_row:

        btn = tk.Button(frame, text=button_text, font="Arial 20 bold")

        btn.pack(side=tk.LEFT, fill=tk.BOTH, expand=True)

        btn.bind("<Button-1>", btn_click)

root.mainloop()

```

Copy and paste this code into a `.py` file and run it using a Python interpreter. This program will create a basic calculator GUI where you can perform arithmetic calculations. It includes buttons for digits (0-9), decimal point (.), basic arithmetic operations (+, -, *, /), equal (=) to calculate the result, and a clear (C) button to clear the input.

Please note that this example is a basic calculator and may not handle all edge cases or error handling scenarios. You can further enhance this GUI by adding features like parentheses, scientific functions, and more advanced operations.
