calculator using python gui

Creating a calculator using a GUI in Python can be done using the Tkinter library. Here is an example of a basic calculator that can perform addition, subtraction, multiplication, and division

import tkinter as tk

def calculate():
first_number = float(first_number_entry.get())
second_number = float(second_number_entry.get())
operation = operator.get()

if operation == "+":
result = first_number + second_number
elif operation == "-":
result = first_number - second_number
elif operation == "*":
result = first_number * second_number
elif operation == "/":
result = first_number / second_number
else:
result = "Invalid Operation"

result_label.config(text="Result: " + str(result))

app = tk.Tk()
app.title("Calculator")

first_number_label = tk.Label(app, text="First Number")
first_number_label.grid(row=0, column=0)

first_number_entry = tk.Entry(app)
first_number_entry.grid(row=0, column=1)

second_number_label = tk.Label(app, text="Second Number")
second_number_label.grid(row=1, column=0)

second_number_entry = tk.Entry(app)
second_number_entry.grid(row=1, column=1)

operator = tk.StringVar()
operator.set("+")

addition_button = tk.Radiobutton(app, text="+", variable=operator, value="+")
addition_button.grid(row=2, column=0)

subtraction_button = tk.Radiobutton(app, text="-", variable=operator, value="-")
subtraction_button.grid(row=2, column=1)

multiplication_button = tk.Radiobutton(app, text="*", variable=operator, value="*")
multiplication_button.grid(row=3, column=0)

division_button = tk.Radiobutton(app, text="/", variable=operator, value="/")
division_button.grid(row=3, column=1)

calculate_button = tk.Button(app, text="Calculate", command=calculate)
calculate_button.grid(row=4, column=0, columnspan=2, pady=10)

result_label = tk.Label(app, text="Result:")
result_label.grid(row=5, column=0, columnspan=2)

app.mainloop()



This creates a simple calculator that allows user to input two numbers, select an operation and then get the result. It uses Tkinter to create the GUI elements, such as labels, entry fields, and buttons. The calculate() function performs the calculation based on the selected operation and the input numbers, and the result is displayed in the result label.
