I want to use recursion to reverse a string in python so it displays the characters backwards (i.e "Hello" will become "olleh"/"o l l e h". I wrote one that does it iteratively: def Reverse( s ): result = "" n = 0. start = 0. while ( s[n:] != "" ): while ( s[n:] != "" and s[n] != ' ' ): n = n + 1. result = s[ start: n ] + " " + result. start = n.
