First of all, you forgot to import random. To import random use import random. Secondly, your argument for your function is a string (words surrounded in either apostrophes or quote marks). Third, when you tried to find the length of the argument, you subtracted 1 in the len function, you can't subtract an integer from a string. Lastly, when you went to return the answer, you returned the string without any sort of square brackets at the end to specify a location in the string. A completed challenge is here:

import random

def random_item(iterable):
    answer = random.randint(0, len(iterable) - 1)
    return iterable[answer]
