老师  为啥我写完后敌方子弹碰到我方坦克后整个画面就卡住不动了呢，也不报错

老师，这个警告是怎么来的？？老师视频咋们不会

老师，为什么这是b的返回值是None

我想问一下调用event.wait（）阻滞了之后，会继续往下走！！，等sleep的时间结束之后，再执行完没有执行的

老师，这个报错什么意思？？我看了代码跟老师的一样的

在代码中这两个是怎么打印的，他们是在哪个步骤被调用打印的呢

老师，查询无结果，跟笔记里面对过没有错，而且我想重试一下然后刷新就要重新登录，重新登录第一次又跳到error出错画面，然后再是一次右好了

请问老师，从哪里可以下载坦克image的图片

var userid=$("#userid").val();
var username=$("#username").val();

选择器不是{}个符号么

userid=().()username=().()

老师我零基础学习这个，到现在能听懂但是一让我自己写就不知道从哪里开始写，是继续听下去还是停下来理解下写。

怎么成乱码了

本节课中，奇数行的背景颜色设置为red，为什么表头的颜色并没有变化呢？

老师，这一节与上一节的添加用户有什么不一样吗，出来形参，效果，作用什么的呢，不太理解

老师，我在这里锁的时候锁属性也可以，也就是说锁什么都行了？在使用的时候有没有什么要注意的地方呀？
