Create a graphical application in Python Tkinter that asks the user to enter two integers and displays their sum as shown in the figure below:

#### Solution

``from tkinter import *# create action methode def action ():    # retrieve the value of the first and second input field    M = int (entryNumber1.get ())    N = int (entryNumber2.get ())            S = M + N    # display the sum in label result    lblResult['text'] = "The Sum is : " + str(M)  + " + " +  str(N) +"  = " + str(S)  # creation of the main windowroot = Tk ()root.geometry ("400x175")# Creation of the first edit control with the associated labellblnumber1 = Label (root, text = "Enter the value of M :")lblnumber1.place (x = 50, y = 20)entryNumber1 = Entry (root)entryNumber1.place (x = 200, y = 20)# Creation of the 2nd input field with the associated labellblnumber2 = Label (root, text = "Enter the value of N :")lblnumber2.place (x = 50, y = 50)entryNumber2 = Entry (root)entryNumber2.place (x = 200, y = 50)# Create a label to display resultlblResult = Label(root)lblResult.place(x = 200 , y = 80)# Creation of button that validates the actionValidate = Button (root, text = "Validate", command = action)Validate.place (x = 200, y = 120, width = 165)                root.mainloop ()``
