轮盘赌程序把现金加起来

Question

Python 3.5

我有一个项目，为一个班创建一个轮盘赌轮迷你游戏，我有问题。我将初始现金设置为100美元，让用户玩轮盘赌。在他们下注后，到了为下一轮计算现金的时候，我在设置新的现金价值时遇到了问题。基本上，我需要把赢/亏加在现金的价值上，这样它就可以准确地更新到下一轮了。我知道把现金作为一个全局变量是错误的，但是我们还没有学会正确的方法来做，也没有时间亲自去检查。不管怎样，这个问题已经接近底部了。谢谢你的帮助！-在

您可以使用已有的方法创建自己的python类。然后可以用参数^{}声明{}一个类变量。使用self.cash可以访问每个方法中的变量。如果这没有帮助，请用你的问题评论这个答案。在
