Generally, problems with RTL text are *display* problems, and are not solved by reversing strings. I've hardly ever needed to reverse a string, and when it does happen, it's generally for the sake of *parsing*. You reverse a string, parse it from left to right, then reverse the result, in order to do a "parse from the right" operation. Never done that in Python, because the situations where that's necessary are (a) rare, and (b) generally suitable for a regex anyway. Does anyone have a really complex parsing job that absolutely cannot be done with a regex, and benefits from reversal?
