Write a function that converts an int num between 0-9 (inclusive) to its string equivalent (i.e., 1 -> "one").

def int_to_word(num):
  if num == 0:
      return "zero"
  if num == 1:
      return "one"
  if num == 2:
      return "two"
  if num == 3:
      return "three"
  if num == 4:
      return "four"
  if num == 5:
      return "five"
  if num == 6:
      return "six"
  if num == 7:
      return "seven"
  if num == 8:
      return "eight"
  if num == 9:
      return "nine"
        
int_to_word(9)
