    >>> def rev(forward):
    ...     backward = list(forward)
    ...     backward.reverse()
    ...     return ''.join(backward)
    >>> rev("spam")
    'maps'

list.reverse() changes the list in-place. Instead of iterating over
the items in the string sequence, you can just convert the input
string outright.
