item.py random_item()

Hi, guys! I'm trying to figure out how to define the length of my iterable - 1, and am wondering if len(I) would be the correct syntax for random.randomint(). I don't think it is, but I think I'm on the right track. Thank you for your help

Pat

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

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

Hi there, yes you are on the right track, however just a small change. I also would not use 'i' . Random.randint will return an integer. So to get the result you will have to return that index of the passed in list i. 

 num = random.randint(0, len(i)-1)

Hope this makes sense
