item.py
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"

import random

def random_item(List):

    li = random.randint(0, len(List) - 1)
    return li

You are very close! Instead of return the random index generated, use the index li to select an item from List:

return List[li]

Also, the preferred style is to use lowercase parameter names and to avoid using built-in keywords and types as variable or parameter names. Try lst or arg or item, etc. instead.

the challenge is giving you the error Didn't get a correct option back from random_item. I did return the iterable with the variable and it worked. Therefore you are returning the iterable with the randomly selected number

return List[li]
