I was able to get the code worked in workspace. However, the exercise here is telling its incorrect.

The below code executes fine in Workspace. The same isn't working in exercise. Thanks! 

import random

def random_item(arg1):
    rand_num = random.randint(0,(len(arg1)-1))
    print("The randomly selected number is {}".format(rand_num))
    arg1_list = list(arg1)

    for letter in arg1_list:
        if arg1_list.index(letter) == rand_num:
            print("The return value would be {}".format(letter))
            break

random_item("Treehouse")

This code may not cause errors, but what it does is different from what the challenge instructions ask for:

  • the challenge does not ask you to "print" anything
  • the challenge does not require formatting strings
  • the challenge does not require a loop
  • the challenge does ask that the function return a single member based on a random index
