Python Python Testing First Steps With Testing Create a Doctest

Add a doctest to average() that tests the function with the list [1, 2]. Because of how we test doctests, you'll need to

python

average.py
import doctest

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

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


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

Remove the numb_list and it will work. Don't need to store that in a variable.

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

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


"""
