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)
``` PLUS

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
