Python Program for Addition, Subtraction, Multiplication and Division operations Using Python GUI

 Python Program for Arithmetic Opeartions using Python GUI

How to create Python GUI ?

A simple way to create the GUI in Python by using the Tkinter Library of Python.

Tkinter provides a fast and easy way to create the GUI applications in Python. Tkinter provides a powerfull object oriented interface to the Tk GUI Toolkit.

Example : 

 import tkinter  # imported tkinter
 win = tkinter.Tk() # object Creation
 win.title("My Window")	# Title of the Window
 win.mainloop()	# run the tkinter

Here we have created a simple window by using tkinter library.

In that, we have create a object of tkinter package as win.

Then, we have gave the title to window by using .title() method.

Program to create Calculator Using Tkinter :

 from tkinter import *

 def addition():
     result = float(bx1.get())+float(bx2.get())
     result = round(result,4)
     lbl4.config(text=result)
    
 def subtract():
     result = float(bx1.get())-float(bx2.get())
     result = round(result,4)
     lbl4.config(text=result)

 def multiply():
     result = float(bx1.get())*float(bx2.get())
     result = round(result,4)
     lbl4.config(text=result)

 def divide():
     result = float(bx1.get())/float(bx2.get())
     result = round(result,4)
     lbl4.config(text=result)
    
 window = Tk()
 window.title("Python Calculator")
 lbl1 = Label(window,text="Enter 1st Number : ")
 lbl1.grid(row=0, column=0)

 lbl2 = Label(window, text="Enter 2nd Number : ")
 lbl2.grid(row=1, column=0)

 lbl3 = Label(window,text="Result : ")
 lbl3.grid(row=2, column=0)

 lbl4 = Label(window,text="")
 lbl4.grid(row=2,column=1)

 bx1 = Entry(window)
 bx2 = Entry(window)

 bx1.grid(row=0, column=1)
 bx2.grid(row=1, column=1)

 b1 = Button(window, text="Addition", width=10, command=addition)
 b1.grid(row=0, column=2, padx=5, pady=5)

 b2 = Button(window, text="Subtract", width=10, command=subtract)
 b2.grid(row=0, column=3, padx=5, pady=5)

 b3 = Button(window, text="Multiply", width=10, command=multiply)
 b3.grid(row=1, column=2, padx=5, pady=5)

 b4 = Button(window, text="Divide", width=10, command=divide)
 b4.grid(row=1,column=3,padx=5,pady=5)

 lbl5 = Label(text="www.computertipstricks.tech for Python GUI Tutorial",
            bg='lightgreen',font=('verdana',12))

 lbl5.grid(row=4, column=0, padx=5, pady=5, columnspan=4)

 window.mainloop()

Online IDE's does not supports Tkinter library, so we aren't able to run the code on this page.

Output : 

Addition : 

Subtraction : 

Multiplication :

Division : 

Hope this program will help you to create a Calculator using Tkinter in Python.
