You've got a few issues here:

  • "remove" is not a string method (you might be thinking of lists)
  • even if you convert the string into a list, "remove" only takes away the first item that matches
  • "lower" does not change the string you apply it to (it creates a new one with the changes)
  • you don't want to lower the entire string anyway, letters not removed should remain as they are

Since strings are immutable, you cannot change it. You can create a new string and return the new one. You can start with an empty string and use a for cicle. If the character is a consonant then add to the new string. After the for cicle return the new string.
