self._say(self._q()) 是什么意思呢

[Royhowtohack]

修改完以后报错了。看了两遍视频，没看懂 self.say()这个函数的意思。报错跟这个也有关。我把整个代码贴在下面。请李老师指教。(｡ì í｡)

现仔细看看 https://github.com/neolee/wop-community 的 README，学会怎么贴代码。你这一大串代码真没法看啊。

_q() 是在 Bot 中定义的方法，Bot 类所有子类，也就是所有小机器人们都要实现这个方法，实现时返回一个字符串就行了，这个字符串会作为该机器人说的第一句话——正如 Bot 类的 run() 方法里实现的那样。

在你的 run() 方法中，它先根据 self.runtype 选择执行 _run_once() 或 _run_loop() 两个之一，而这两函数的实现都没问题；但你的问题在于，为啥后面还有一堆老代码没清除掉呢？这些老代码里没使用 _q() 方法，还在使用已经移除的 self.q 属性，那就自然要出问题了。

[Royhowtohack]

我试了把run里面后面的代码都注释，也报错了。

我没有找到self._say()这个函数在哪里定义的，返回去看了视频，还是没搞懂self._say()的作用。_q()的作用搞懂了。

哪里来的？上课讲过的啊，现场演示了的一个方法。
