'''以前店子词典上有个游戏：要你猜一个4位密码，密码由0-9组成，不重复。才对正确位置上的数字为A，猜到数字但位置不正确为B，每次显示答案中A和B的个数。'''

pa = ['1','2','3','4','5','6','7','8','9','0',]
password = sample(pa,4)
#print password
mypass = '4A0B'
result = ['']*4

while ''.join(result) != mypass:
        result = ['']*4
        i = 0
        j = 0
        text = raw_input('Please guess the password of 4 unrepeated numbers 0-9:')
        for x,y in zip(text,password):
                if x == y:
                        i += 1
        for z in text:
                if z in password:
                        j += 1

        result[0] = str(i)
        result[1] = 'A'
        result[2] = str(j - i)
        result[3] = 'B'
        print ''.join(result)
else:
        print mypass

试了一下，貌似OK... 支持crossin...
