python - Saving down onto a file and sorting after highest score! Pyhton games -

update: added said

class highscorehandler(object):  highscore_file = "highscores.txt"  # define store highscores  def get_highscores(self, sort=true):  # return sorted default     open(self.highscore_file, "a+") f:  # open highscore file         f.seek(0)  # rewind file start         scores = [int(x) x in f.read().split()]  # read scores ints         if sort:  # sort if required             return sorted(scores)  # add reverse=true `sorted()` descending sort         return scores  def save_highscore(self, highscore):     highscores = set(self.get_highscores(false))  # current highscore list     if highscore in highscores:  # highscore exists         return  # nothing do...     highscores.add(highscore)  # add highscore set     open(self.highscore_file, "w") f:  # open highscore file writing         f.write(" ".join(str(score) score in highscores))  # store scores 

and put save_highscoreand get_highscores "code" part

# display final score. drawboard(mainboard) scores = getscoreofboard(mainboard) print('x scored %s points. o scored %s points.' % (scores['x'], scores['o'])) if scores[playertile] > scores[computertile]:     print('you beat computer %s points! congratulations!' % (scores[playertile] - scores[computertile]))     highscore =  scores[playertile] - scores[computertile]     get_highscores()     save_highscore() elif scores[playertile] < scores[computertile]:     print('you lost. computer beat %s points.' % (scores[computertile] - scores[playertile])) else:     print('the game tie!')  if not playagain():     break 

but yet try save highscore file tells mename 'get_highscores' not defined

you can create 2 functions - 1 read scores, update them if needed. simplest way store simple set (to weed out duplicates) , retrieve when needed (and optionally sort if need show scores in sorted manner:

highscore_file = "highscores.txt"  # define store highscores  def get_highscores(sort=true):  # return sorted default     open(highscore_file, "a+") f:  # open highscore file         f.seek(0)  # rewind file start         scores = [int(x) x in f.read().split()]  # read scores , turn them int         if sort:  # sort if required             return sorted(scores)  # add reverse=true `sorted()` descending sort         return scores  def save_highscore(highscore):     highscores = set(get_highscores(false))  # current highscore list     if highscore in highscores:  # highscore exists         return  # nothing do...     highscores.add(highscore)  # add highscore set     open(highscore_file, "w") f:  # open highscore file writing         f.write(" ".join(str(score) score in highscores))  # store space separated scores 

then can use 2 functions hearts content manage highscores as:

print(get_highscores())  # [], no highscores yet save_highscore(5)  # add 5 print(get_highscores())  # [5] save_highscore(12)  # add 12 save_highscore(6)  # add 6 save_highscore(8)  # add 8 print(get_highscores())  # [5, 6, 8, 12] save_highscore(6)  # add 6 again print(get_highscores())  # [5, 6, 8, 12], doesn't save duplicate scores 

update - can turn these functions class methods adding self attribute first method and, if keep highscore_file class property, referring self.highscore_file, like:

class highscorehandler(object):      highscore_file = "highscores.txt"  # define store highscores      def get_highscores(self, sort=true):  # return sorted default         open(self.highscore_file, "a+") f:  # open highscore file             f.seek(0)  # rewind file start             scores = [int(x) x in f.read().split()]  # read scores ints             if sort:  # sort if required                 return sorted(scores)  # add reverse=true `sorted()` descending sort             return scores      def save_highscore(self, highscore):         highscores = set(self.get_highscores(false))  # current highscore list         if highscore in highscores:  # highscore exists             return  # nothing do...         highscores.add(highscore)  # add highscore set         open(self.highscore_file, "w") f:  # open highscore file writing             f.write(" ".join(str(score) score in highscores))  # store scores 

then can run same way referring instance of it:

handler = highscorehandler() print(handler.get_highscores())  # [], no highscores yet handler.save_highscore(5)  # add 5 print(handler.get_highscores())  # [5] handler.save_highscore(12)  # add 12 handler.save_highscore(6)  # add 6 handler.save_highscore(8)  # add 8 print(handler.get_highscores())  # [5, 6, 8, 12] handler.save_highscore(6)  # add 6 again print(handler.get_highscores())  # [5, 6, 8, 12], doesn't save duplicate scores
