Sep 1, 2020

#### Exercise 198

Create a graphical application with Python Tkinter which tests whether a given integer is a perfect square or not as shown in the figure below:

#### Solution

``from tkinter import *def action():    N = int(entryNumber.get())    # create a counter to test if the number is perfect square    j = 0    for i in range(0,N):        if(i**2 == N):            j = i            break    if j > 0:        lblDisplay['text'] = str(N) + " is perfect square " +  str(N)  + " = " + str(j) + " ^ 2"    else :         lblDisplay['text'] = str(N) + " is not perfect square! "           #lblDisplay['text'] = "Welcome " + name + " !"    # You can also use the following syntax :    #lblDisplay.configure(text = "Welcome " + name + " !")root = Tk()root.geometry("400x170")# Create Label and Entry NamelblNumber = Label(root , text= "Enter integer N : " , width = 20 )lblNumber.place(x = 10 , y = 20)entryNumber = Entry(root)entryNumber.place(x = 175 , y = 20 , width = 175)# Create label to display resultlblDisplay = Label(root , text='...........')lblDisplay.place(x = 175 , y = 120)# Create button to execute actionbtnAction = Button(root , text = "Validate"  , command = action)btnAction.place(x = 175 , y = 70 , width = 175)root.mainloop()``
