need help answer is almost right

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

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

"""
return sum(num_list)
```

It's asking for an average. You're half way there.

• You'll need to use the len() function on num_list to return the length of the list.

• Then divide sum(num_list) by len(num_list).

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

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

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

thank you so much that worked, NOTE: had to delete all empty space lines and then add the spacing in the lines in between average and after the 1.5 and it finally worked.

Note after numbers hit enter and after 1.5 hit enter must have a line of space

def average(num_list): """ Return the sum of a list of numbers >>> average([1, 2]) 1.5
""" return sum(num_list) / len(num_list)

That's weird but I'm glad you got it working, Cheers!
