python - 自动摘要仅返回第一句 - Python / Flask

Question

尝试创建一个使用多种算法自动总结文章的网站。遇到仅从选择中提取第一句话的问题，感谢您提供任何帮助。

我正在使用作为摘要库的库 sumy，并使用烧瓶和 HTML/CSS 从算法中输出自动摘要。除了 LSA，唯一的输出是第一句话，让我相信这与我的“para”变量有关。我创建它是因为它附加了字符串以创建完整的段落，但我确信有一种更简单的方法可以做到这一点。

   @app.route('/dependent', methods = ['POST'])
def mySumD():
if request.form['action'] == 'LSA':
    para = ""
    url = request.form['url_link']
    parser = HtmlParser.from_url(url, Tokenizer(LANGUAGE))
    stemmer = Stemmer(LANGUAGE)
    summarizer = Summarizer(stemmer)
    summarizer.stop_words = get_stop_words(LANGUAGE)

    for sentence in summarizer(parser.document, SENTENCES_COUNT):
        data = str(sentence)
        para += data 
    return render_template('dependent.html', para = para)

elif request.form['action'] == 'Luhn':
    para = ""
    url = request.form['url_link']
    parser = HtmlParser.from_url(url, Tokenizer(LANGUAGE))
    stemmer = Stemmer(LANGUAGE)
    summarizer = LuhnSummarizer(stemmer)
    summarizer.stop_words = get_stop_words(LANGUAGE)

    for sentence in summarizer(parser.document, SENTENCES_COUNT):
        data = str(sentence)
        para += data 
        return render_template('dependent.html', para = para)

elif request.form['action'] == 'LexRank':
    para = ""
    url = request.form['url_link']
    parser = HtmlParser.from_url(url, Tokenizer(LANGUAGE))
    stemmer = Stemmer(LANGUAGE)
    summarizer = LexSummarizer(stemmer)
    summarizer.stop_words = get_stop_words(LANGUAGE)

    for sentence in summarizer(parser.document, SENTENCES_COUNT):
        data = str(sentence)
        para += data 
        return render_template('dependent.html', para = para)
