如何抓取网络新闻并将段落合并到每篇文章中

我正在从该网站抓取新文章https://nypost.com/search/China+COVID-19/page/2/?orderby=relevance我使用 for 循环来获取每篇新闻文章的内容，但我无法组合每篇文章的段落。我的目标是将每篇文章存储在一个字符串中，所有字符串都应该存储在我的文章 list.

When I 打印（我的文章[0]），它给了我所有的文章。我希望它应该给我一篇文章。

任何帮助将不胜感激！

            for pagelink in pagelinks:
                #get page text
                page = requests.get(pagelink)
                #parse with BeautifulSoup
                soup = bs(page.text, 'lxml')
                containerr = soup.find("div", class_=['entry-content', 'entry-content-read-more'])
                articletext = containerr.find_all('p')
                for paragraph in articletext:
                    #get the text only
                    text = paragraph.get_text()
                    paragraphtext.append(text)
                    
                #combine all paragraphs into an article
                thearticle.append(paragraphtext)
            # join paragraphs to re-create the article 
            myarticle = [''.join(article) for article in thearticle]
    
    print(myarticle[0])

        #scrape the links of the articles
        for i in containers:

            atitle = i.find(class_ = 'entry-heading').find('a')
            thetitle = atitle.get_text()
            title.append(thetitle)
            for pagelink in pagelinks:
                #get page text
                page = requests.get(pagelink)
                #parse with BeautifulSoup
                soup = bs(page.text, 'lxml')
                containerr = soup.find("div", class_=['entry-content', 'entry-content-read-more'])
                articletext = containerr.find_all('p')
                for paragraph in articletext:
                    #get the text only
                    text = paragraph.get_text()
                    paragraphtext.append(text)
                    
                #combine all paragraphs into an article
                thearticle.append(paragraphtext)
            # join paragraphs to re-create the article 
            myarticle = [''.join(article) for article in thearticle]
    
    print(myarticle[0])

print(scrape('https://nypost.com/search/China+COVID-19/page/'))

你不断地追加到现有的列表 [] 中，它不断增长，你需要在每个循环中清除它。

    articletext = containerr.find_all('p')
    for paragraph in articletext:
        #get the text only
        text = paragraph.get_text()
        paragraphtext.append(text)

    #combine all paragraphs into an article
    thearticle.append(paragraphtext)
# join paragraphs to re-create the article 
myarticle = [''.join(article) for article in thearticle]

应该是这样的

    articletext = containerr.find_all('p')
    thearticle = [] # clear from the previous loop
    paragraphtext = [] # clear from the previous loop
    for paragraph in articletext:
        #get the text only
        text = paragraph.get_text()
        paragraphtext.append(text)

    thearticle.append(paragraphtext)
    myarticle.append(thearticle)

但你可以将其进一步简化为：

article = soup.find("div", class_=['entry-content', 'entry-content-read-more'])
myarticle.append(article.get_text())
