NameError for function name

I think errors shown to students should be more descriptive:

import random def random_item(args): return args.index(random.randint(0,len(arg)-1))

I don't know why I get a name error for the function name

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

Youre almost there. Your return statement is a little off. Try this (you can use args instead of iterable):

import random

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

`The randomly selected number is 4.

The return value would be "h"

import random def random_item(args): return args[random.randint(0,len(arg)-1)]`

random_item is not found
