基于Python实现简单排行榜功能

class Leaderboard:

        if player_name in self.leaderboard_data:

    def get_top_scores(self, num_scores):
        sorted_leaderboard = sorted(self.leaderboard_data.items(), key=lambda x: x[1], reverse=True)
        return sorted_leaderboard[:num_scores]
    
    def get_player_rank(self, player_name):
        sorted_leaderboard = sorted(self.leaderboard_data.items(), key=lambda x: x[1], reverse=True)
        player_rank = [x[0] for x in sorted_leaderboard].index(player_name) + 1
        return player_rank

# 获取前两名玩家和排名

print("Top 2 Scores:", top_scores)

​​​​​​​alice_rank = leaderboard.get_player_rank("Alice")
