first_and_last_4 issue

HI Team Treehouse,

I've tried to test my code with atom and it's working to produce the output but when I hit "recheck work" in the coding challenge workspace it's throwing "Bummer: Couldn't find first_4".

Any guidance would be appreciated, thank you!

slices.py 
x = list(range(20))

def first_and_last_4(x):
    first_4 = x[:4]
    last_4 = x[-4:]
    pieces = (first_4 + last_4)
    return(pieces)

I thinks it's because you modified the first_4 function on the first task in order to complete this task? You need to create a new function for the second task. Also your function argument can just be x. There's no need for a value. Hope this helps.

Thank you Zach that link was helpful.

Leo, somewhat I've realised I've deleted the first_4 function that's why the grader was looking for it I've reloaded the first_4 function together with the first_and_last_4 and was able to get it done.

Thank you for all the inputs!
