推荐答案

没错，名称不能在关键字参数的形式被用来指定命名的属性名称因为名称名称已用于 BeautifulSoup 本身。所以改用：

Yep, name can't be used in keyword-argument form to designate an attribute named name because the name name is already used by BeautifulSoup itself. So use instead:

soup.findAll(attrs={"name":"description"})

这是什么 ATTRS 参数是作为：传递作为一个字典的属性，而您不能使用关键字参数的形式，因为限制他们的名字是Python关键词或以其他方式采取BeautifulSoup本身！

That's what the attrs argument is for: passing as a dict those attribute constraints for which you can't use keyword-argument form because their names are Python keyword or otherwise taken by BeautifulSoup itself!
