# Solution Exercise 201: Get the divisors of an integer N graphically in python tkinter

Aug 25, 2020

#### Exercise 201

1. Write a program in Python that lists all divisors of a given integer N.
2. Create a program in Python that which a Tkinter window asking the user to enter an integer N and returns all the divisors of N.

#### Solution

1. List of divisors of an integer N

``def listDivisors (N):    # initialization of the list of divisors  L = []    L = []    # We browse throught the integers: 1 2 3 ... N    for i in range (1, N + 1):        # we test if the integer i is a divisor of N and we add it to the list of divisors L        if N% i == 0:            L. append (i)    return L# We test the algorithmprint ("The list of divisors of 18 is :", listDivisors (18))# Displays: The list of divisors of 18 is : [1, 2, 3, 6, 9, 18]``

2. List of divisors graphically in python tkinter

``from tkinter import * # method that performs the actiondef action ():        # retrieve the value of the edit control    N = int (entryNumber1.get ())    lblDivisors ['text'] = 'The  divisors  of  N    :    '        # find the divisors s of n by going through all the integers from 1 to n    for i in range (1, N + 1):        if ( N%i == 0 ):            lblDivisors ['text'] = lblDivisors ['text'] + "   " + str(i) + "   "# Creation of the main windowfen = Tk ()fen.geometry ("400x175")# input field for the integer N with the associated labellblnumber1 = Label (fen, text = "Enter the value of N")lblnumber1.place (x = 10, y = 20)entryNumber1 = Entry (fen)entryNumber1.place (x = 200, y = 20)# Label which gets the resultlblDivisors = Label (fen, text = "The divisors of N : ")lblDivisors.place (x = 10, y = 50)# validation buttonValidate = Button (fen, text = "Validate", width = 20, command = action)Validate.place (x = 200, y = 90)fen.mainloop ()``
