687 PointsCan't figure out what I'm doing wrong
I'm not sure how exactly to return the character of the index, if this is the way im not sure what im doing wrong. Please help
# EXAMPLE
def random_item('bar'):
index= random.randint(0,len(bar)-1)
return index
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"

15,604 PointsSure, Ferdous.
Firstly, you want to make sure you import the necessary library or module directly before you call it in your function.
import random
or:
from random import randint
Secondly, instead of returning the random index, you need to return the character of the string ('foo' in this case) at that random index! We can do this by subscripting the string passed through the function (bar).
example:
character = string[index]
in this case we need to:
from random import randint
def random_item(bar):
index = randint(0, len(bar) - 1)
return bar[index]
Hope this helps! -Charles
