It works when I run it, but it will not pass the challenge. Changing the two last lines to return iterable[::2] pass, but it should give the same result. Or is there actually some difference in the returned material that is not obvious when printed, but may be significant later?
def first_4(iterable):
return iterable[0:4]
def first_and_last_4(iterable):
return iterable[:4] + iterable[-4:]
def odds(iterable):
return iterable[1::2]
def reverse_evens(iterable):
even_iterable = iterable[1::2]
return even_iterable[-1::-1]

#yours
def reverse_evens(iterable):
even_iterable = iterable[1::2]
return even_iterable[-1::-1]
#fixed
def reverse_evens(iterable):
even_iterable = iterable[::2]
return even_iterable[-1::-1]
