在Python

Question

因此，我必须使用卡片对象重新制作纸牌游戏War。我遇到的问题是如何比较两个卡对象列表，看看哪个更大。我没有尝试过比较两个列表的任何东西，因为我真的不知道从哪里开始。我需要比较哪一个更大，并给予该名单/人获胜的积分。一个ace是1但是击败了一个13岁的国王我在课堂上有重载方法，因为我知道这是从哪里开始的，但这是我到目前为止所做的：

import random
class War:
    def __init__(self):
        randomCard = random.randint(1,13)
        self._cNumber = randomCard
        randomSuit = random.randint(1,4)
        self._cSuit = randomSuit

        if self._cSuit == 1:
            self._cSuit = "H"
        elif self._cSuit == 2:
            self._cSuit = "S"
        elif self._cSuit == 3:
            self._cSuit = "C"
        elif self._cSuit == 4:
            self._cSuit = "D"


    def getNumber(self):
        return self._cNumber

    def getSuit(self):
        return self._cSuit

    def __str__(self):
        if self._cNumber > 1 and self._cNumber < 11:
            return str(self._cNumber) + self._cSuit
        elif self._cNumber == 1:
            return "A" + self._cSuit
        elif self._cNumber == 11:
            return "J" + self._cSuit
        elif self._cNumber == 12:
            return "Q" + self._cSuit
        elif self._cNumber == 13:
            return "K" + self._cSuit

    def __gt__(self,other):
        if self._cNumber == 1:
            self._cNumber = 14
        if other._cNumber == 1:
            other._cNumber = 14

        if self._cNumber > other._cNumber:
            return True


    def __lt__(self,other):
        if self._cNumber == 1:
            self._cNumber = 14
        if other._cNumber == 1:

        return False

    def __eq__(self,other):

            self._cNumber = 14
        if other._cNumber == 1:
            other._cNumber = 14

        if self._cNumber == other._cNumber:
            return True
        return False

对于重载战争游戏的卡片方法，您只需要关注卡片的等级而不是套装，以下内容可能适用于此...

def cmp(self, other):
    if self.rank > other.rank: return 1
    if self.rank < other.rank: return -1
    return 0

def __eq__(self, other):
    return self.cmp(other) == 0

def __le__(self, other):
    return self.cmp(other) <= 0

def __ge__(self, other):
    return self.cmp(other) >= 0

def __gt__(self, other):
    return self.cmp(other) > 0

def __lt__(self, other):
    return self.cmp(other) < 0

def __ne__(self, other):
    return self.cmp(other) != 0 

在编写Card类之前，您可能还想要实现Deck类，Hand类和War类。至少需要Card类来利用以前发布的代码，因为它将两个对象（卡片）作为参数
