I am very new to this and not sure what I am doing wrong, any help would be much appreciated. Here is the question:
You've seen how random.choice() works. It gets a random member from an iterable (like a list or a string). I want you to try and reproduce it yourself. 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. Check the file for an example.
import random
def random_item("treehouse"):
random_number = random.randint(0, len("treehouse") - 1)
return random_number[index]
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"

Treehouse Guest TeacherFunction parameters, the things inside of parentheses after the function name, should be valid variable names and not strings. Then, inside your function, you'll need to use that same variable name to find the length of the string that gets passed in.
For your current example, if we fix the parameter name, you still have an issue below where you're using len(). What if the string that comes in is the word "hello"? You could get a random number higher than 4!
