Write a function that returns True if exactly one word in the list differs in length from the rest. Return False in all other cases.
odd_one_out(["silly", "mom", "let", "the"]) ➞ True
odd_one_out(["swanky", "rhino", "moment"]) ➞ True
odd_one_out(["the", "them", "theme"]) ➞ False
odd_one_out(["very", "to", "an", "some"]) ➞ False
The length of the list will always have at least three or more words.
