Make a new function named first_and_last_4. It'll accept a single iterable but, this time, it'll return the first four a
why this still showing not "didn't get the right value for first_and_last_4" I will be happy if anyone show my mistake
def first_4(iterable): return iterable[:4] def first_and_last_4(iterable): first=iterable[1:] last=iterable[-1:] result=first+last return result

You did the first_4 function correctly and needed to put that as it is in the first_and_last_4
def first_4(iterable): return iterable[:4] def first_and_last_4(iterable): first=iterable[:4] last=iterable[-4:] result=first+last return result
In the first_and_last_4 function, for the first 4 part you need to set STOP as index 4 so it will loop from beginning as default and end at index 4 and for the last 4 you need to set START as -4 so it will go one step from -4 ahead each time and end at the last value with default step of 1
