Python Python Collections (Retired) Slices Slice Functions

Is there some crazy slice to get the first_4 and last_4 all in one slice?

I ended up having to do something like this:

def first_4_and_last_4(itr):
    first_4 = itr[:4]
    last_4 = itr[-4:]
    return first_4 + last_4

There isn't some crazy slice to get both the first 4 and last 4 in one step is there?

Hi undefish

I dont know any particular method that would just give your the first 4 and last 4 of an iterable.

just refactored your code a bit

def first_4_and_last_4(itr):
    return itr[:4]+itr[-4:]
