这次要分享的内容十分简单，但也可以算是我们以后写东西可能会经常用到的一个小工具，就是关于如何爬取百度文库对应某个词汇的词条数，也就是拥有的页面量。(The content to be shared is very simple, but it can also be a small tool that we will often use to write later. It's about how to crawl the number of entries that Baidu library corresponds to a word, that is, the amount of pages it owns.)
