写一个打气球的游戏代码气球上面的数字和运算符号对应积分

以下是一个简单的打气球游戏代码，每个气球上的数字和运算符号对应不同的积分值，玩家可以通过点击气球来打破它们并获得相应的积分。游戏结束后，玩家可以看到自己的得分和排名。

import random

class Balloon:
    def __init__(self):
        self.number = random.randint(1, 10)
        self.operator = random.choice(['+', '-', '*', '/'])
        self.points = self.get_points()

    def get_points(self):
        if self.operator == '+':
            return self.number
        elif self.operator == '-':
            return -self.number
        elif self.operator == '*':
            return self.number * 2
        elif self.operator == '/':
            return self.number // 2
        else:
            return 0

class Game:
    def __init__(self):
        self.balloons = []
        self.score = 0
        self.rankings = []

    def start_game(self):
        for i in range(10):
            balloon = Balloon()
            self.balloons.append(balloon)

        self.play_game()

    def play_game(self):
        for i, balloon in enumerate(self.balloons):
            print(f"Balloon #{i+1}: {balloon.operator}{balloon.number}")
            pop = input("Do you want to pop this balloon? (y/n) ")
            if pop.lower() == 'y':
                self.score += balloon.points
                print(f"You got {balloon.points} points!")
            else:
                print("You missed this balloon.")

        print(f"Game over! Your final score is {self.score}")

        self.update_rankings()

    def update_rankings(self):
        self.rankings.append(self.score)
        self.rankings.sort(reverse=True)
        print("Rankings:")
        for i, score in enumerate(self.rankings):
            print(f"{i+1}. Score: {score}")

if __name__ == '__main__':
    game = Game()
    game.start_game()

这个游戏中，每个气球的数字和运算符号都是随机生成的。玩家可以选择是否打破每个气球，如果打破了，就会获得相应的积分。最后，游戏结束后会显示玩家的得分和排名
