Question

Python Write a program that asks the user for an integer and then prints out all its factors.

Answer 1

Answer:

def display_factors(num):

   for counter in range(1, num+1):

       if num % counter == 0:

           print(counter)

int_num= int(input("Enter a number : "))

print("The factors for {} are : ".format(int_num))

display_factors(int_num)

Explanation:

The function display_factors is used to display all factors of a number entered by a user.

• In this  for counter in range(1, num+1) the for loop is iterated until counter is greater  to num is false.   Counter variable starts from 1 and ends when it gets greater than the input number.

• if num % counter == 0: In this statement, each loop  iteration, checks whether a number (num) is exactly divisible by counter. It is the condition for counter to be a factor of num.

• print(counter) This is used to display factors of an input number

• int_num= int(input("Enter a number : ")) This statement asks user to enter a number (int_num) which will be an integer.

• display_factors(int_num) This calls display_factors number to find the factors of an input number.
