When i input def random_item(iterable): it shows NameError: name 'iterable' is not defined

When i input 

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

it shows NameError: name 'iterable' is not defined

But wen i input

import random
def random_item(iterable_thing):
    return iterable_thing[random.randint(0,len(iterable_thing)-1)]

it is correct

What is the different between "iterable" & "iterable_thing"?

Neither one of those works for me (but I get a different error message).

But both will work if you change "randint" to "random.randint", or if you change "import random" into "from random import randint".

Thanks Steven,

Its Typing error.. i add back the random now,

the one with (iterable) Shows -- "NameError: name 'iterable' is not defined" and the one with (iterable_thing) -- "Correct"

Whats the different with iterable and iterable_thing..?

There's no difference other than the name itself. As I said, both work for me after correction.
