  """Exercise 4: Divisors.
  
  Create a program that asks the user for a number and then prints out a
  list of all the divisors of that number. (If you don’t know what a
  divisor is, it is a number that divides evenly into another number. For
  example, 13 is a divisor of 26 because 26 / 13 has no remainder.)
