The reversed built-in function returns a reverse iterator. The object's __reversed__ magic method is called by the reversed built-in to implement reverse iteration. Python reverse listIn the first example, we reverse a Python list with the reverse method and the [::-1] operator. reverse_...
Now use the while loop to iterate and store each element in the new list with each iteration decrementingidxuntil it hits0. whileidx>=0:newList.append(numbers[idx])idx=idx-1print(newList) Output: [52, 44, 105, 34, 17, 97, 45, 2, 78, 66] ...

On the next iteration of the loop, the output is "i is 47 , message[i] is d , translated is .d". You can see that i has been decremented from 48 to 47, so now message[i] is message[47], which is the 'd' string. (That’s the second 'd' in 'dead'.) This 'd' gets ...
