Elif 打印错误消息

Question

我之前问过类似的问题，但解决方案似乎不起作用。我正在编写一款掷骰子游戏，如果任何一个玩家的数字与计算机的数字匹配，则玩家获胜，并打印一条消息“你赢了”。否则，elif 语句意味着计算机获胜并打印“你输了”。我的问题是 elif 语句不会打印“你输了”。它只是不断打印“你赢了”。import randomdie1 = 0die2 = 0die3 = 0roll1 = 0roll2 = 0roll3 = 0def dice_roll():    dieroll = random.randint(1, 6)*2    return dierollfor die in range(12):    die1 = int(input(f'Choose a number between 2 and 12: '))    die2 = int(input(f'Choose a number between 2 and 12: '))    die3 = int(input(f'Choose a number between 2 and 12: '))    roll1 = dice_roll()    roll2 = dice_roll()    roll3 = dice_roll()    if die1 or die2 or die3 == roll1 or roll2 or roll3:        print(f'Roll # 1 was {roll1}')        print(f'Roll # 2 was {roll2}')        print(f'Roll # 3 was {roll3}')        print(f'You Win! - Thanks for playing!')    elif die1 or die2 or die3 != roll1 or roll2 or roll3:        print(f'Roll # 1 was {roll1}')        print(f'Roll # 2 was {roll2}')        print(f'Roll # 3 was {roll3}')        print(f'You Lose! - Thanks for playing!')

Answer 1

在 for 循环内部，if 语句的参数声明不正确。这是一个帮助澄清这一点的示例：

a=1

b=3

if a or b == 2:

   print(True)

else:

   print(False)

上面示例中的 if 语句将始终打印True，因为您询问以下问题：“如果a的值是 True/大于 0或如果b等于 2：打印 True” 在您的情况下：

if die1 or die2 or die3 == roll1 or roll2 or roll3

您将参数声明为“如果 die1、roll2 或 roll3 有任何 True/大于 0 值，或者如果 die3 等于 roll1：...”，因此只需将其更改为您希望它们与 Abhigyan 进行比较的实际值Jaiswal 的回答说它会正常工作。

Answer 2

如果你想检查是否有任何die1, die2, die3匹配， roll1, roll2, roll3那么你可以使用：

print(f'Roll # 1 was {roll1}')

print(f'Roll # 2 was {roll2}')

print(f'Roll # 3 was {roll3}')

if {die1, die2, die3} & {roll1, roll2, roll3}:

    print('You win. Thanks for playing.')

else:

    print('You lose. Thanks for playing.')

这会检查 的集合{die1, die2, die3}和 的集合是否{roll1, roll2, roll3}有任何共同元素。

另外，顺便说一句，random.randint(1, 6)*2这并不等于掷两个骰子。它是掷骰子，结果加倍；因此所有奇数都被排除，并且概率被展平。如果你想模拟掷两个骰子，你需要random.randint(1,6) + random.randint(1,6).

Answer 3

添加到 khelwood 的答案中，如果您喜欢这种语法，可以使用此方法

从你的代码逻辑来看，当玩家至少做出 1 次正确的猜测时，他们似乎会自动获胜（我不确定这是否是你的意图）。

if die1 == roll1 or die2 == roll2 or die3 == roll3:

    print(f'Roll # 1 was {roll1}')

    print(f'Roll # 2 was {roll2}')

    print(f'Roll # 3 was {roll3}')

    print(f'You Win! - Thanks for playing!')

else:

    print(f'Roll # 1 was {roll1}')

    print(f'Roll # 2 was {roll2}')

    print(f'Roll # 3 was {roll3}')

    print(f'You Lose! - Thanks for playing!')

Python 评估由关键字分隔的每个条件。非空值将始终返回 True

因此，如果您正在执行此方法

elif die1 or die2 or die3 != roll1 or roll2 or roll3:

die1 die2 roll2 roll3总是返回 True，这就是导致你的程序总是打印“你输了”的原因

Answer 4

#You can do this as well

  

  if die1 == roll1 or die2 == roll2 or die3 == roll3:

    print(f'Roll # 1 was {roll1}')

    print(f'Roll # 2 was {roll2}')

    print(f'Roll # 3 was {roll3}')

    print(f'You Win! - Thanks for playing!')

  else:

    print(f'Roll # 1 was {roll1}')

    print(f'Roll # 2 was {roll2}')

    print(f'Roll # 3 was {roll3}')

    print(f'You Loose! - Thanks for playing!')
