Trying this code for the solution of the challenge, i get a reversed but splitted list and the challenge cannot be completed. Unfortunately i just get something could not be reversed... What do i have to do to not get a splitted list?
backwards = [
'tac',
'esuoheerT',
'htenneK',
[5, 4, 3, 2, 1],
]
def reverse(iterableitem):
revitem = []
for item in iterableitem[::-1]:
revitem.append(item)
return revitem
forwards = list(map(reverse, backwards))

8,605 PointsKenneth !!! ....... :) Ok, found it, you need to leave the list () call out. Found the same in the challenge for filters.

def reverse(word):
return word[::-1]
forwards = list(map(reverse, backwards))
UPDATE: Ok, now I see you didn't make a list, just added one to the list, but still - map gives one item at a time so you don't have to use "for" loop :)

8,605 PointsThanks, for the hint. I was confused about the returned results by running it in my Python IDE. I ran your suggestion in the IDE and it worked as expected. Unfortunately using Code in the Challenge, it tells me that "forwards isn´t a map" ...... weired.

29,446 PointsWeird... I've just ran
backwards = [
'tac',
'esuoheerT',
'htenneK',
[5, 4, 3, 2, 1],
]
def reverse(word):
return word[::-1]
forwards = list(map(reverse, backwards))
An it pass the challenge.

def reverse(word):
return word[::-1]
forwards = list(map(reverse, backwards))

Treehouse Guest TeacherBecause you made a list.

3,743 PointsHere's my code. I was sure this was correct, and after checking the threads, it seems to be the popular answer. However, I am not passing the code challenge. Any insight? I'm getting Bummer! Not all items were reversed correctly. I'm inquiring about challenge 2 of 2 (forwards).
backwards = [ 'tac', 'esuoheerT', 'htenneK', [5, 4, 3, 2, 1], ]
def reverse(thing): return list(reversed(thing))
forwards = map(reverse, backwards)

Treehouse Guest TeacherI'd tell you to send back a list if that was what I wanted :)
