Great job! :thumbsup: There are many errors, though. These ar all the errors I can count:

  • The random.randint's first argument should be 1, not 0.
  • There is no such function called "index", you get indexes like this:
# Get the first index
some_list[0]
  • Assign the index to a variable so that you can use it later
  • Don't call the random_item function inside the random_item function, or it will be recursive

You should end up like this:

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

import random

def random_item(my_list):
    random_index = random.randint(1, len(my_list)) - 1
    return my_list[random_index]

Hope that helps! :dizzy:
