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

what am I missing here

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)

Hello, Natasha Hove

Ummm ... The doctest format is off at multiple places

  • should not leave blank line between test case & expected output
  • needs to have a space between >>> and average = (1, 2)
  • average = (1, 2) is not a function call.
  • lastly, average function takes a list as argument, your code gives 2 numbers as arguments instead.
def average(num_list):
    """Return the average for a list of numbers

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

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

That should fix the problem.

Thank you very much William Li...i got it to work
