Question

我阅读并尝试this，this和this解决方案。但我的错误没有解决。

    def read_news(self, news_url):
    try:
        self.checkRequests(news_url)
        result = self.soup.find("div", {'class', 'm-article__entry'})
        if isinstance(result, bs4.element.Tag):
            for r in result:
                re.sub("<.*?>", "", r)
            print ('result', result)
            return result.lower()
        return
    except Exception, e:
        self.insertErrorLog('thevergetech.read_news', news_url, e)

这是代码发生错误的部分。我在调试模式下运行我的代码，结果返回：

    <div class="m-article__entry">
<p>Malloy Aeronautics, a UK-based company, has been slowly and publicly developing a hoverbike over the last few years — it even used <a href="https://www.kickstarter.com/projects/1524806320/hoverbike/description" target="new">Kickstarter</a> to raise funds. But it looks like the project is now headed in a new direction, because the US Department of Defense just announced a deal with Malloy to develop the vehicle for the US Army.</p>
<p>The DoD is interested in the technology for a few reasons. For one, it's safe. The hoverbike's rotors are guarded so they won't tear into humans and other objects. It's also a cheaper option than, say, a helicopter. And it's more maneuverable in tight spaces, with options to operate it autonomously or with a human pilot.</p>

<p>Developers of the hoverbike <a href="http://www.reuters.com/article/2015/06/22/us-airshow-france-hoverbike-idUSKBN0P21C720150622?feedType=RSS&amp;feedName=technologyNews">told Reuters</a> that they consider it ideal for search and rescue or cargo delivery missions. It could also be used for surveillance — plans for the full-scale version include an attachable humanoid figure with a head-mounted camera.</p>
<p>The first step in the deal will be to build a functioning full-scale model, and from there the DoD will reportedly design military-grade prototypes. In the meantime, Malloy Aeronautics will continue to make scale models while developing a commercial version of the hoverbike.</p>

我尝试循环就像for r in return一样，但循环2次并得到同样的错误。

Answer 1

我修复了我的代码。这段代码没有错误;

def read_news(self, news_url):
        try:
            self.checkRequests(news_url)
            result = self.soup.find("div", {'class', 'm-article__entry'})
            if isinstance(result, bs4.element.Tag):
                result = str(result)
                result = re.sub("<.*?>", "", result)
                return result.lower()
            return
        except Exception, e:
            self.insertErrorLog('thevergetech.read_news', news_url, e)
