Python 石头剪刀-从数学上获得冠军

我刚刚用python完成了我的石头剪刀游戏。现在，用户必须在三个按钮之间进行选择，字符串

user1

被设置为“石头”、“布”或“剪刀”。 当我评估游戏时，代码只运行一些if语句，例如检查

if computer == "Paper"

但是如果我想用我自己的物品来扩展游戏，那就需要很多“如果/否则”。Sow我想我应该给每个项目一个唯一的数字，这样我就可以使用这个数字，而不必乱弄字符串

我的老师给了我一个提示，让我把这两个整数分开，以决定谁赢

但是在我考虑了一段时间之后，我没有找到任何解决办法来解决这个问题。这只是关于这背后的逻辑，我不想要任何代码

我怎样才能用两个整数作为项目，仅仅通过一点数学就找到赢家呢？

谢谢大家!

假设我们正在使用普通的石头剪刀，正如您在对问题的评论中所说的那样。让我们分配：

Rock:     0
Paper:    1
Scissors: 2

这个答案假设你知道模运算符（

%

），所以如果不知道，请先查一下它的意思。我在这个答案中使用了它，所以当我们将1添加到剪刀（即2）中时，得到的是0，而不是3，因为石头是0，数字3没有项目

通过将数字分配给选择，我们希望选择在对方选择之后获胜，在对方选择之前失败，在双方平等的情况下平局。例如，2紧跟在1之后，所以剪刀胜过纸。我们将使用模运算符确保数字保持在1和3之间（包括1和3）

所以，如果你想确定玩家1是否获胜，你应该检查他们的移动是否比玩家2的移动大1。要判断他们是否平手，看他们是否有相同的动作。如果这两个都不是真的，那么玩家2一定赢了。下面是一个带有一些测试的示例实现：

>>> def winner(p1, p2):
...   if (p1+1) % 3 == p2:
...     return "Player 2 won because their move is one greater than player 1"
...   elif p1 == p2:
...     return "It's a draw because both players played the same move"
...   else:
...     return "Player 1 wins because we know that it's not a draw and that player 2 didn't win"
...
>>>
>>>
>>> rock = 0
>>> paper = 1
>>> scissors = 2
>>> winner(rock, paper)
'Player 2 won because their move is one greater than player 1'
>>> winner(paper, scissors)
'Player 2 won because their move is one greater than player 1'
>>> winner(scissors, rock)
'Player 2 won because their move is one greater than player 1'
>>> winner(rock, scissors)
"Player 1 wins because we know that it's not a draw and that player 2 didn't win"
>>> winner(paper, paper)
"It's a draw because both players played the same move"

在这个游戏中，数学规则是，一个项目以比它小1的数字（模3）击败该项目。如果你增加更多的项目，你需要拿出一个数学规则来控制游戏的运作方式。一个例子（这不是很有趣）是保持一个规则，即一个项目击败项目1的次数少于它（因此输给项目1的次数多于它），并与任何其他项目保持平局，尽管这将是一个相当无聊的游戏

希望这个答案有帮助！！祝你好运

解决这一问题的一个更简单的方法是为赢和输条件制作两个字典，然后将用户输入指定为键，将计算机输入指定为字典中的值

rps_win={'rock':'scissor','paper':'rock','scissor':'paper'}
rps_lose={'rock':'paper','paper':'scissor','scissor':'rock'}

然后检查用户计算机对是否来自赢或输字典，并相应地添加分数

if rps_win[b]==a:
    player=player+1//incrementing player points
    print('win point!')
elif rps_lose[b]==a:
    comp=comp+1//incrementing computer points
    print('lose point!')
else:
    print('tie!')

你的问题到底是什么？问题编辑@Rob。我只想通过使用一点整数来获得取决于两个整数的获胜者math@DirtyDev你还没有解释如何选择获胜者。你说你想添加你自己的项目，这些项目会有数字，但我们不知道什么数字会超过什么数字，如果没有这些信息，我们就不可能帮助你编写算法，因为我们甚至不知道算法应该做什么。@ChristopherShroba okay sry。假设这是一把普通的石头剪刀
