导语

我第一次玩24点是初中的时候，那时候和堂弟表哥在堂妹家玩，堂妹提出玩24点游戏，堂妹比我们小三岁，可能正在上小学吧。

拿出一副扑克牌去掉大小怪和花牌，从剩下的牌里随便找出四张，谁能先用加减乘除算出24就算赢。

如果大家都同意放弃或者有人计算出来就重新开始一局。结果是我们三个哥哥都输多赢少，堂妹显然是经过了准备的。

其实24点小游戏除了能用来无聊的时候跟朋友与一起玩儿下，还能锻炼思维能力，尤其是家里的小孩子提升数学能力

多锻炼还是很有好处的，尤其是那些数学不好小孩子——可提高心算的速度和准确度，当数学变成游戏之后孩子也更有兴趣嘛~今天木木子就带大家写一款有界面的“24点小游戏”哦

游戏介绍

（1）什么是24点游戏

棋牌类益智游戏，要求结果等于二十四

（2）游戏规则

任意抽取4个数字（1——10），用加、减、乘、除（可加括号）把出现的数算成24。每个数字必须用一次且只能用一次。“算24点”作为一种锻炼思维的智力游戏，还应注意计算中的技巧问题。计算时，我们不可能把牌面上的4个数的不同组合形式——去试，更不能瞎碰乱凑。

例:3、8、8、9

答案:3×8÷(9-8)=24

实现代码

1.定义游戏这部分代码小写game.py文件
