am i right?
def first_4(raw):
return raw[:4]
def first_and_last_4(raw):
first_4=raw[:4]

Python Development Techdegree Student 36,887 PointsHi Travis,
You've identified the right numbers to output, but not the correct data type. You should be preserving the data type of the input iterable, just like you've done in the first challenge. So if the challenge passed ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i'] (list of strings) into your function, you would pass back a list of strings, specifically, ['a', 'b', 'c', 'd', 'f', 'g', 'h', 'i']. Similarly, if your function was given a list of integers, such as [1, 2, 3, 4, 5, 6, 7, 9, 10], you should return a list of integers: [1, 2, 3, 4, 7, 8, 9, 10].
If your function received a tuple input (like you are describing with your 'my_array'), such as (1, 2, 3, 4, 5, 6, 7, 8, 9, 10), the slice function will preserve that data type and will also produce a tuple, so the correct output in that case would be (1, 2, 3, 4, 7, 8, 9, 10).
Right now you are returning a string, regardless of the input.
Hope that points you in the right direction
Cheers
Alex
