  i = 0
  new_string = ""
  while i &lt; len(secret_word):
      j = 0
      print(1)
      for j in old_letters_guessed:
          if secret_word[i] == old_letters_guessed[j]:
              new_string += secret_word[i]
          print(old_letters_guessed[j])
          j += 1
      print(secret_word[i])
      i += 1
  return new_string
  </code></pre>
