def random_item("Treehouse"): random.randint(0, len("Treehouse" - 1) return("Treehouse")
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"
def random_item("Treehouse"):

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]
