slices.py question

Soo... I think I know what's going on here but need a little push in the right direction.

z = [1, 2, 3, 4, 5]

print(z[1::2]) print(z[-1::-2])

This code has the output of:

treehouse:~/workspace$ python pop.py [2, 4] [5, 3, 1]

So I've been trying to come up with the reason that it isn't working in the challenge and the only thing that I can think of is that I'm assuming the list in the challenge because I can't actually see it.... Can someone please point me straight?

Thank you

Hi Christian,

Can you link to the challenge? Not sure what the objective is.
