Unsure on what to do next

I'm stuck on this quiz. I don't know how to generate the random number which is minus 1 the length of the word and also how to print out the index related to the number in the word. Please help!

item.py
# EXAMPlE
import random

random_item("Overwatch")
random.randint(len(random_item)




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

There are a few steps missing.

ā€¢ you need to create a function named random_item that takes a single argument, an iterable. Remember to start with the def statement

ā€¢ To get the random number minus 1 add a "-1" inside your parents

random.randint(len(arg)-1)

ā€¢ Remember to assign this to a variable so it can be used to grab the correct character.

ā€¢ Finally use a return statement either the proper result

Post back if you need more help. Good luck.

import random # -> import the random library
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"

# -- create random_item function --
def random_item(word):
    random_index = random.randint(0, len(word)-1) # -> use the random.randint() function to get the index
    return word[random_index] # -> return a random item by using your random index

# -- call the random_item function --
print(random_item("Treehouse")) # -> calls the function and immediately prints its output to the console
