卡在while循环

Question

我想为我的侄子做一个骰子tosser，所以他可以玩没有骰子的棋盘游戏。即使我输入了一个真实的条件，我也陷入了一个while循环。我试图让他选择他想用的骰子，但是如果他选择了一个错误的骰子，那么它会要求他再次输入。我的代码是...

dice_select = input('Enter the amount of sides are on the dice you want to throw, either 4, 6, or 12: ') 
while dice_select != 4 or dice_select != 6 or dice_select != 12: 
    dice_select = int(input('Sorry thats not quite right. Enter the amount of sides are on the dice you want to throw, either 4, 6, or 12: ')) 

如果我输入4,6或12，那么当它应该继续时，它仍然使我进入循环。

Answer 1

试试这个：

dice_select = int(input('Enter the amount of sides are on the dice you want to throw, either 4, 6, or 12: ')) 
    while not (dice_select == 4 or dice_select == 6 or dice_select == 12): 
     dice_select = int(input('Sorry thats not quite right. Enter the amount of sides are on the dice you want to throw, either 4, 6, or 12: ')) 

这意味着循环，直到dice_select等于4,6或12

随着你的计划，你的while循环的条件永远是正确的，因为当它等于4，你的程序正在检查错误或真实或真实，这将永远是真实的。

换句话说，您的程序正在寻找何时dice_select等于4,6和12的时间。这是不可能的。
