# 入口函数
if __name__ == '__main__':
    # 让a, b, c三人分别遍历x, y, z，并将重复出现的对阵及题目提供的对阵给去除即可。
    for a in ["x", "y", "z"]:
        for b in ["x", "y", "z"]:
            for c in ["x", "y", "z"]:
                if a != b and b != c and c != a and a != "x" and c != "x" and c != "z":
                    # 对阵名单
                    print("a对阵%s, b对阵%s, c对阵%s" % (a, b, c))
