Succeed without if statement?

Greetings! Does anyone know if there's a way to accomplish the fourth step, just using slicing? I was able to do it with len() and an if statement, but not with only slicing... Thoughts?

Thanks all!!!

One approach could be to get first all even index numbers and then reverse that list, this way:

 def reverse_even(iterable):
    return iterable[::2][::-1]

I hope this helps you,
