For the part 4 of this challenge, my code does not work, but when I write this on my workspace, it works...
On my workspace it looks like this:
def reverse_evens(iterable): return iterable[::-2] print(reverse_evens(input("What is your iterable: ")))
def first_4(iterable):
return iterable[0:4]
def first_and_last_4(iterable):
one = iterable[0:4]
two = iterable[-4:]
return one + two
def odds(iterable):
return iterable[1::2]
def reverse_evens(iterable):
return iterable[::-2]

- set the starting position based on the length (even or odd) of the list
- take the even indexed items first, then reverse them as a separate operation
Either method will work when correctly implemented, but the second one is a bit easier to do.
