You're returning number while the challenge wants a letter in the word that is fed to the function. Based on your code if you call it right now like this: random_item("example") you'll get random numbers like 3, 4, 1 etc. The goal is to get the letter associated with that number. I would refactor it like this:

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

# or shorter but less readable 
def random_item(iter):
    return iter[random.randint(0, len(iter) -1)]
