每次我运行程序时，它似乎都在不同的地方，我不确定为什么。我非常接近完成这部分工作，这使我发疯。有人可以在他们的机器上运行它，让我知道他们的想法吗？我试图用不同的if语句来控制范围，但是过一会儿它变成一堆废话。

答案 0 :(得分：0)
我不确定这是否是您的错误的根源，但我确实注意到了这一点
random_roll = random.randint(upper_bound-2, upper_bound) # Randomly selects a number from 1 to 4 to be used as fair die roll
使用upper_bound = 4，它将是random.randint(2, 4)，而不是(1, 4)，就像您想要的那样。
但是，我也同意DYZ的评论，即您应该将程序分成多个函数，而不是将其全部包含在多个if语句的单个循环中。
