Python Python Basics (2015) Letter Game App Random Item

How is this incorrect?

"First, import the random library. Then create a function named random_item that takes a single argument, an iterable. Then use random.randint() to get a random number between 0 and the length of the iterable, minus one. Return the iterable member that's at your random number's index"

Those are my instructions, and I believe I followed them correctly; however, it says that the name "random_item" is not defined. I dont understand, because it is a function that I am currently defining, please help.

import random

numbers = (0, len(ite))-1
item_list = list(ite)

def random_item(ite):
    return item_list[random.randint(numbers)]

Hi Jonathan!

The thing about this code challenge is that it is possible to do it all inside the function (other than the import of course). It would go something like this:

import random

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

Things to note:

  1. No need to turn the utterable into a list, you can return something based on an index in a string. For example the letter at index 3 of the word "Blanket" would be "n"
  2. There is no need to create a range for the random.randint method. You enter the range in the parentheses when you call the method.
