I don't understand what you are trying to do. At all. The usual way to use a dictionary for a tic tac toe game is to number the squares from zero through 8, or 1 through 9, so those are the keys of a dictionary. The user selects a square number and the dictionary is updated with an X or O for that key (square number) . You can then check squares 1 ,2, 3 (and all of the other winning combinations) to see if they are all equal.
