Courses Plus Student 2,103 PointsI'm stuck in the random..
I know I'm close, but I can't do it..
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"
import random
def random_item(arg):
random_arg = random.randit(0, len(arg)-1)
return arg.index(random_arg)

Treehouse Moderator 68,457 PointsYou have right approach. Three errors need fixing.
- typo should be
random.randint
-
return
statement is indented too far. It should align with statement above it. - to reference the index of a container object use square brackets (also called braces):
arg[random_arg]
Post back if you need more help. Good luck!!!

Thank you again!
import random
def random_item(arg):
random_arg = random.randint(0, len(arg)-1)
return arg[random_arg]

Courses Plus Student 2,103 PointsHi Chris,
Thank you for your time.
I followed you instructions and I received this error:
Bummer! TypeError: 'builtin_function_or_method' object is not subscriptable
This is saying I haven't imported the random?!
