How to make the Calculator in python

This tutorial will teach you how to make the simple calculator in python programming.This programming will be able add,subtract,multiply,divide two numbers.

from tkinter import *

def Add():
    result = int(e1.get()) + int(e2.get())
    resultText.set(result)

def Min():
    result = int(e1.get()) - int(e2.get())
    resultText.set(result)


def Sub():
    result = int(e1.get()) * int(e2.get())
    resultText.set(result)

def Div():
    result = int(e1.get()) / int(e2.get())
    resultText.set(result)

root = Tk()
root.title("Calculator")
root.geometry("300x200")

global e1
global e2
global resultText

resultText = StringVar()

Label(root, text="Num1").place(x=10, y=10)
Label(root, text="Num2").place(x=10, y=40)
Label(root, text="Result:").place(x=10, y=60)

e1 = Entry(root)
e1.place(x=100, y=10)
e2 = Entry(root)
e2.place(x=100, y=40)

result = Label(root, text="", textvariable=resultText).place(x=100, y=80)

Button(root, text="+", command=Add ,height = 1, width = 2).place(x=10, y=100)
Button(root, text="-", command=Min ,height = 1, width = 2).place(x=40, y=100)
Button(root, text="*", command=Sub ,height = 1, width = 2).place(x=80, y=100)
Button(root, text="/", command=Div ,height = 1, width = 2).place(x=120, y=100)

num1 = Entry(root)
num2 = Entry(root)

root.mainloop()
