Python 彩票游戏
这是我第一次完全自己做的项目，没有参考任何教程，我知道做得有点粗糙。目前，我搞不清楚为什么我的奖金总是显示为“盒子”类型的投注奖金。我也还没完全弄明白如何表示5位数字的盒子类型投注，所以那部分程序还没写好。如果有人能帮我解决这个投注类型的问题，我会很感激。

这个
if self.betType.upper() == 'BOX' or 'BOXED' or 'B'
不等于
if (self.betType.upper() == 'BOX') or (self.betType.upper() == 'BOXED') or (self.betType.upper() =='B')
第一个会计算三个不同的表达式：
if (self.betType.upper() == 'BOX') # either True or False
if ('BOXED') # this will ALWAYS evaluate to True
if ('B') # this will also always evaluate to True
所以如果你把这些用or连接起来，你总是会得到真。你需要像第二种方法那样，逐个完整比较每个字符串。

Python中的比较操作可能和你想的有点不一样：
if self.betType.upper() == 'STRAIGHT' or 'S':
这相当于
if (self.betType.upper() == 'STRAIGHT') or ('S')
'S'是一个非零的实体，所以它的值是True - 你可以试试看：
if 'S':
print('huh?')
关于你代码的其他部分，有个一般性的建议：你不需要把玩家使用的数字位数当作字符串来处理 - 如果self.digits是一个数字会更好，这样可以让你的代码更符合Python的风格 - 看看能不能根据digits的值动态改变choice，而不需要使用单独的if语句。（作为提示，可以研究一下“列表推导式”）
祝你编码愉快！
