     我发帖的时间是我五升六年级的时候，我三年级开始创作这个内容，修改了无数次，放到我的海龟编辑器里了，叫“PyWord2.0”，我希望可以给需要的人提供一些帮助，谢谢。话不多说，看代码！

time.sleep(0.3)
print("    共10个关键字    对%s个  错%s个" % (t, 10 - t))
time.sleep(0.3)
if (t < 10 and t > 0):
    pas("            错 词 表 ：", 0.3)
    for j in 喵:
        print("         %s" % j)
        time.sleep(0.1)
print("    用时%ss  历史记录：%ss" % (t2, maxt))
time.sleep(0.3)
if (t == 10):
    if (t2 < maxt):
        print("你打破了历史记录,比旧记录快%.1fs！" % (maxt - t2))
    else:
        print("   成绩不错，离历史纪录还差%.1fs！" % (t2 - maxt))
else:
    print("   只有满分才可以和历史记录对比哦！")

（注意第15行的maxt变量是可以改的！指的是历史记录！）
