def reverse_reversed(items): Create|and return a new list that contains the items in reverse, but so that whenever each item is itself a list, its elements are also reversed. This reversal of sublists must keep going on all the way down, no matter how deep the nesting of these lists, so you ought to use recursion to solve this problem. The base case handles any argument that is not a list. When the items parameter is a list (use the Python function type or the isinstance operator to check this), recursively reverse the elements that this nested list contains. (List comprehensions might come handy in doing this part of the problem.) Note that this function must create and return a new list to represent the result, and should not rearrange or otherwise mutate the contents of the original list. This same principle should apply to all functions that receive a list argument. In your own programs that compute some important list that you pass to some function from the standard library, isn't life easier when you never have to worry of that function silently mutating the contents of your list? Expected result [5, ['yeah', 4, 3, 21, 1] items [1, [2, 3, 4, 'yeah'], 5] [נננ[[2 ,1זזtttt נננ[[[1 ,2וזזזtt [42, [99, [17, [33, ['bool']]]]][[[[['bool'], 33], 17], 991, 42]

Please help solve the python problem, thank you
