Add a doctest to average()...

Help!

I'm pretty sure that the answer is correct (sum = 3, len = 2) All I get is 'Bummer! Try again!' which isn't very helpful.

Thanks

average.py 
def average(num_list):
    """Return the average for a list of numbers

    >>>average([1, 2])
    1.5

    """
    return sum(num_list) / len(num_list)

this is silly, but I think your only problem is that you need a space between >>> and average
