Question

我正在尝试玩 uno

试试这个：if __name__ == "main": main()，现在我得到这个错误； NameError：名称 'Deck' 未定义

import random

class UnoCard:
    def __init__(self, c,n):
        self.color = c

            return "green" + str(self.n)
        if self.c == 1:
            return "yellow" + str(self.n)
        if self.c == 2:
            return "blue" + str(self.n)
        if self.c == 3:
            return "red" + str(self.n)
    def canPlay(self,other):

    def printResult(self):
        print (hand1)
        print (hand2)

def main():
    my_game = Uno()
    my_game.playGame()

我在 Windows 10 日用 Anaconda 写的。当我运行它时程序自动关闭。我没有得到任何输出..

我认为您构建套牌的方式不正确。

您在 makeDeck 函数中没有 Deck 变量。相反，您想像这样将卡添加到自身

def makeDeck(self):
    duplicates = 2
    for num in range (1,10):
        for color in ["Yellow", "Red", "Blue", "Green"]:
            newcard = UnoCard(color,num)
            for _ in range(duplicates):
                self.addCard(newcard)

此外，color 必须是数字而不是字符串才能使 self.c == 0 行起作用，实际上应该是 self.color == 0。没有self.c或self.n

注意：UNO 有跳过、反转和荒野
