文曲星上的“猜数字”游戏Python版

文曲星上的经典“猜数字”游戏，伴我度过了多少个无聊的时该，今天回想起来，依然心潮澎湃。前几天将这个游戏做到到Winodows Mobile上。今天赶上有空，又将它写成了Python。哈哈，Python不愧为Python,只用到前者1/3左右的代码就搞定了。
说一下游戏规则吧，很简单：程序随机生成一个数字不重复的四位数（如1234），要求玩家在8次机会内猜出这个答案。每次竞猜，程序会以“XAXB”的形式提示玩家，其中“A”表示数字和位置都正确，“B"表示位置不正确但数字正确，“X”表示相应的个数。如玩家猜“5678”,那么提示为“0A0B”,猜“4321”则“0A4B”，当“4A0B”时，即4个数的位置的数字都正确了，才算胜利！
怎么样？你敢挑战一下自己的智商吗？以下是源码：（欢迎帮助改进，最好能改成PYS60上的）
