Python Python Basics (Retired) Pick a Number! Any Number! Imports

I dont see whats wrong with my code (Now make a function named random_num that takes an int argument...)

I keep getting an error that says "can't seem to call random_num() with an argument."

import random
list = [1,2,3,4,5]
def random_num(list):
    return random.randint(1, len(list)-1)

The challenge is looking for a number to be passed in, not a list:

import random

def random_num(num):
    return random.randint(1, num)

The argument being passed in is an int representing the upper range of the random number. Getting rid of the call to len should help.

You also won't need to define any input to be passed in. The challenge will deal with that.

Great! it worked.Thanks guys.
