First things first. Our first task is to import random and create a function. Functions are created by using:

def name_of_the_function(arguments):

That function has to be named random_item and it has to take one argument (its name is up to you). So the following code will now look like:

import random

def random_item(iterable):
    ...

And now the most important part - the functionality itself. We need to use the random.randint() to get a random number between 0 and the length of the iterable that will be passed to it. Iterable is something that you can iterate through so it can be a list, tuple or a dictionary. It's basically something that holds more variables at once(more numbers, strings etc.).

And now you just have to get a random number between 0 and the length of the iterable and return a member of the iterable itself that has the index of the random number.

So the following code will look like:

import random

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

Feel free to ask if there's something that you still don't understand.
