Python+Pygame怎么实现24点游戏

这篇文章主要介绍了Python+Pygame怎么实现24点游戏的相关知识，内容详细易懂，操作简单快捷，具有一定借鉴价值，相信大家阅读完这篇Python+Pygame怎么实现24点游戏文章都会有所收获，下面我们一起来看看吧。

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
