where am l getting it wrong..
Create a function named reverse that takes a single iterable item and returns a reversed version of that item
backwards = [ 'tac', 'esuoheerT', 'htenneK', [5, 4, 3, 2, 1], ] def reverse(iters): iters = ['this'] modified = list(map(reverseStr,iters)) return modified

Did you peek ahead at code for task 2? You won't need "map" for task 1.
Here's a few hints:
- the "reverse" method should work with the argument, it should not replace it with literal data
- it should work with any kind of iterable (strings, lists, tuples, etc)
- a handy mechanism that works with all iterable types is a slice

Create a function named reverse that takes a single iterable item and returns a reversed version of that item.
Here we'll create our function - reverse - that takes in our list - backwards - and returns our reversed version. We'll do this by iterating through the list with a -1 step to reverse the order.
backwards = [ 'tac', 'esuoheerT', 'htenneK', [5, 4, 3, 2, 1], ] def reverse(iters): return iters[::-1]
Now use map() to create a variable named forwards. forwards should use reverse() to reverse the order of every item in backwards.
Now that we've got our function done, we'll come back to the global scope to create our forwards variable. Here we'll use map() to place in our function - reverse - and the object we want to iterate through - backwards.
backwards = [ 'tac', 'esuoheerT', 'htenneK', [5, 4, 3, 2, 1], ] def reverse(iters): return iters[::-1] forwards = map(reverse, backwards)
