The random number should be selected inside the function, and the range should be based on the size of the argument instead of any fixed value.

The code challenge is asking you to give a random number between 0 and the length of the iterable provided as the argument minus 1. To do this you need to use the built in python function, len() to determine the length of the incoming argument. Remember, functions are reusable code snippits. They are useful because you don't always know what the input will be. In this case they could give you an iterable (string, list, etc) that is 10 characters in length and another time you could get an iterable that 15 characters in length. Your function should be capable of handling both.

You should not be declaring any variables outside your function. In fact, you can even complete the challenge without declaring a variable.
