python - Python 中的石头、布、剪刀(大于和小于)

Question

有没有一种方法可以用大于号和小于号来做剪刀石头布游戏？

我知道执行 RPS 有不同的方法，但我想具体了解大于和小于。

这是我的代码:

"Rock" > "Scissors" and 'Rock' < 'Paper'
"Paper" > "Rock" and 'Scissors' < 'Rock' 
"Sissors" > "Paper" and 'Paper' < 'Scissors'
choose1 = input("Player One, Enter your answer ")
choose2 = input("Player Two, Enter your answer ")

if choose1 == "Paper":
    "Paper" > "Rock"
if choose1 == "Scissor":
    "Scissor" > "Rock"


if choose1 != "Rock" and choose1 != "Paper" and choose1 != "Scissors":
    print("Player one please chose Rock, Paper, or Scissors")

if choose2 != "Rock" and choose2 != "Paper" and choose2 != "Scissors":
    print("Player two please chose Rock, Paper, or Scissors")

if choose1 > choose2:
    print('Player1 ({}) beats ({})'.format (choose1, choose2))
else:
    print('Player2 ({}) beats ({})'.format (choose2, choose1))

游戏运行正常，但是，它认为石头打败一切，布只打剪刀，剪刀打不败任何东西。

如何修复此代码以使其正确执行？

Answer 1

如果你真的想用<和 > ，制作类，简单的字符串将不符合您的需求。

class Rock:
    def __gt__(self, other):
        return isinstance(other, Scissors)

class Paper:
    def __gt__(self, other):
        return isinstance(other, Rock)

class Scissors:
    def __gt__(self, other):
        return isinstance(other, Paper)


CHOICES = {
    "rock": Rock(),
    "paper": Paper(),
    "scissors": Scissors()
}

a = CHOICES["rock"]
b = CHOICES["scissors"]

print("player a wins:", a > b)

编辑:或者只用一个类可能更好

class RPS:
    table = {
        "rock": "scissors",
        "paper": "rock",
        "scissors": "paper"
    }

    def __init__(self, what):
        self.what = what
        self.winsover = self.table[what]

    def __eq__(self, other):
        return self.what == other.what

    def __gt__(self, other):
        return self.winsover == other.what


a = RPS("rock")
b = RPS("scissors")

print("player a wins:", a > b)
