Stuck on this one. I have tried 3 different (VERY SIMILAR) variations of the attached code/screenshot and am not getting it solved. I am thinking the problem is that the 'return'?
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"
import random
def random_item(num):
random.randint(0, len(num - 1))
return(random.randint)

565 PointsI'm lost. don't know what you just said, but I tried this and it did not work.
import random def random_item(num): iterable = random.randint(0, len(num - 1)) random.randint(0, len(num - 1)) return(iterable)

231,269 PointsIt's hard to understand that unformatted, but it looks like you're calling random.randint twice instead of just once. But it does look like you're saving the first call in a variable named "iterable". Instead of returning that directly, you should use it as an index value for the argument ("
num[iterable]").And when posting code, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area.
