<p>我甚至不知道该如何提问，因为这似乎需要大量代码才能了解细节。我将讨论运行时的行为，而不是显示代码。在</p>
<p>我使用请求从一个在线数据库获取信息。当我运行for循环遍历我的所有条目时，在前20个条目中的一个（通常是第一个条目，但不一定总是）出现如下错误。列表中的条目都是一样的（只是不同的ID号）。我使用sleep（）来确保不会超出速率限制（我尝试将睡眠时间增加到荒谬的等待时间，但仍然得到错误）。真正让我吃惊的是，它确实起了作用，然后就卡住了。。。。是什么原因造成的？在</p>
<p>另外，代码之前还在工作，然后我对同一文件中的其他代码进行了大量编辑，但我认为我没有编辑任何与此相关的内容。在</p>
