8,872 PointsReturn first four and last four, items from a list, as a single value?
will add up the total value of the required items.
def first_4(your_list): return sum(your_list[:4] + your_list[-4:])
will return the required items in a single list
def first_4(your_list): return your_list[:4] + your_list[-4:]
I must be misunderstanding the question?
def first_4(your_list):
return sum(your_list[:4] + your_list[-4:])

21,526 PointsThe question isn't asking for the sum of the first and last 4 values in the list, it's asking for a new list containing the first and last 4 items from the original list.
sum() isn't required to concatenate lists. You can simply return slice1 + slice2.
Also, as Alexander mentioned, the function needs renamed.

65,469 Points- The function should be called
first_and_last_4, notfirst_4(Remember: the other function you defined was called that!) - Usage of the
sumfunction is unnecessary and in fact with cause an error
Other than those two problems, everything looks fine.
