阅读关于使用正则表达式解析html的文章，简而言之：不要这样做！。您可能想在解析HTML之前对其进行解码。@NimaAzhdari bs4是导入BeautifulSoup的名称。您确定安装正确吗？您应该使用pip来完成此操作。打开一个终端并运行pip安装beautifulsoup4。@NimaAzhdari请检查最后一次编辑。我试过了，现在它可以正常工作了。@NimaAzhdari的确，那是因为url包含等号。。。我正在寻找修复方法。@NimaAzhdari我编辑了我的帖子，以便向您展示for循环的扩展版本href'是html中标记的属性之一，它是保存url的属性。如果tag是一个BeautifulSoup标记对象，那么它的attrs成员将保存其html等价物的属性，因此如果href位于tag.attrs中，那么我想获取它的值，即tag.attrs['href']。tag['href']是tag.attrs['href']的缩写。@NimaAzhdari是的，你似乎是对的。。。老实说，我使用BeautifulSoup只有两个星期，而且只在一个小项目中使用过，结果证明它非常棒！。至于我是如何认识Python的。。。嗯，我大约四年前开始编写代码，差不多三年前我学会了Python。我喜欢它，我用它做了很多项目，从小到小。我读了很多关于StackOverflow的文章，因为我发现很多事情都非常有趣和令人惊讶，你知道while else的语法吗？？，所以我注册并尝试解释我知道的事情，同时也学到了新的东西。
