  from sumy.parsers.plaintext import PlaintextParser
  from sumy.nlp.tokenizers import Tokenizer
  from sumy.summarizers.lsa import LsaSummarizer as Summarizer

      parser = HtmlParser.from_url(url, Tokenizer(LANGUAGE))
      # or for plain text files
      # parser = PlaintextParser.from_file("document.txt", Tokenizer(LANGUAGE))
      stemmer = Stemmer(LANGUAGE)
  
      summarizer = Summarizer(stemmer)
      summarizer.stop_words = get_stop_words(LANGUAGE)
  
      for sentence in summarizer(parser.document, SENTENCES_COUNT):
          print(sentence)
  &lt;/code&gt;
  
  
  For an example with  a working source code that how to apply proxy
  ex:
  &lt;code&gt;
  HTTP_PROXY = {
          "http": "xxx.xxx.xxx.xxx:8800",
          "https": "xxx.xxx.xxx.xxx:8800",
      }
  fetch = requests.get("http://www.independent.co.uk/news/uk/politics/barack-obama-says-david-cameron-allowed-libya-to-become-a-s-show-a6923976.html", proxies=HTTP_PROXY)
      proxy_lookup = requests.get("https://httpbin.org/ip", proxies=HTTP_PROXY)
  
      html = BeautifulSoup(fetch.content, 'html.parser') #full content # lxml
      meta_title = html.title.string
  &lt;/code&gt;
  
  Thanks in advance
