Python纸牌游戏错误

Question

好吧，脚本运行了，但我没有收到任何错误，而且它无法正常工作。更具体地说，该程序应该发牌，然后制作一个字典，根据等级和花色为每张牌赋予一个值。牌被洗牌、发牌，然后排序。谁拥有3C，谁先开始。计算机如何挑选牌是它遍历其牌列表，如果它发现一张牌的价值高于前一张牌，它就会播放它。好吧，有时会起作用，但如果我打出一张牌（通常是 T(10) 或更高），它就不起作用，计算机会打出一张价值较低的牌。感谢您的阅读：D

为了确定计算机是否应该打牌，您可以使用

for i in player.hand:
    if i > previous[-1]:
        playCard(player, i)
        return

“3C”和“TD”等简单的字符串。所以当你使用“>”时比较，它将它们作为字符串进行比较。但作为字符串 'TD' > “QD”等。您可能应该编写一个小函数来确定卡的价值并使用其结果。

PS：你能看到下面还有其他问题吗？

player1 = player(deck[0::2], 'player1')
player2 = player(deck[1::2], 'player2')
player3 = player(deck[2::4], 'player2')
player4 = player(deck[3::4], 'player3')
