python - Ping Pong simulation not correctly triggering function -

i'm new oop , practicing putting little bit more complex programs using various classes , implementing principles inheritance. i've created ping-pong simulation has player class contains probability player win serve. have pingpong class subclass of super class racquetsports. each instance single game, ability change server, , record won, , whether or not shut-out. finally, have simstats class purpose record stats across "n" number of games.

my problem seems play_game function not correctly firing, when place print statement in there never triggers. current result when running whole program player1 has 10 wins no shutouts, , player2 has 0 of both.

finally, suggestions on better oo practice appreciated. here player class:

from random import random   class player(object):      def __init__(self, prob_win):         self.prob = prob_win         self.points = 0      def wins_serve(self):         return self.prob >= random()      def add_point(self):         self.points += 1      def get_score(self):         return self.points 

my racquetsports class:

from abc import abcmeta, abstractmethod player import player   class racquetsport(object):      __metaclass__ = abcmeta      def __init__(self, prob1, prob2):         self.player1 = player(prob1)         self.player2 = player(prob2)         self.server = self.player1      def play_game(self):         while not self.game_over():             self.sim_point()      @abstractmethod     def type(self):         pass      def chg_server(self):         if self.server == self.player1:             self.server = self.player2         else:             self.server = self.player1      def sim_point(self):         if self.server.wins_serve():             self.server.add_point()         else:             self.chg_server()      @abstractmethod     def game_over(self):         pass      def get_scores(self):         return self.player1.get_score(), \                self.player2.get_score()      def return_stats(self):         p1_score, p2_score = self.get_scores()         print(p1_score, p2_score)         won = 'p1'         if p2_score > p1_score:             won = 'p2'         return won, self.__shutout(p1_score, p2_score)      @staticmethod     @abstractmethod     def __shutout(score1, score2):         pass 

my pingpong , simstats classes, calling code:

from racquet import racquetsport   class pingpong(racquetsport):      def type(self):         return 'ping pong'      def game_over(self):         return self.player1.get_score == 11 or \                self.player2.get_score == 11      @staticmethod     def __shutout(score1, score2):         return abs(score1 - score2) == 11   class simstats(object):      def __init__(self):         # first field games won, second shutouts.         self.gms_won_p1 = [0] * 2         self.gms_won_p2 = [0] * 2      def update(self, game):         won, shutout = game.return_stats()         if won == 'p1':             self.gms_won_p1[0] += 1             if shutout:                 self.gms_won_p1[1] += 1         else:             self.gms_won_p2[0] += 1             if shutout:                 self.gms_won_p2[1] += 1      def print_results(self):         tot_games = self.gms_won_p1 + self.gms_won_p2         print('wins player 1 = {} shutouts = {}\n'               'wins player 2 = {} shutouts = {}'.format(*tot_games))   if __name__ == '__main__':     stats = simstats()     x in range(1, 11):         game = pingpong(.5, .5)         stats.update(game)     stats.print_results() 

your first problem never call play_game. guess intend work this:

if __name__ == '__main__':     stats = simstats()     x in range(1, 11):         game = pingpong(.5, .5)         game.play_game()         stats.update(game)     stats.print_results() 

next, have bug cause entire game last forever. take @ these lines:

def game_over(self):     return self.player1.get_score == 11 or \            self.player2.get_score == 11 

get_score function, need call it:

def game_over(self):     return self.player1.get_score() == 11 or \            self.player2.get_score() == 11
