Os arquivos criados podem ser salvos em HTML e PDF ou compartilhados no  IPython Notebook Viewer . Bom, né? O vídeo abaixo dá uma visão geral da ferramenta:

The example URL we’re given is  http://imgur.com/r/funny The code uses  requests  to fetch the HTML and  BeautifulSoup  with  html5lib  to parse it. If you don’t have these install already you can use install them using  pip  e.g. pip install beautifulsoup4 requests html5lib --user One thing to note is that  imgur.com has an api . You use it, taking the blue pill—the article ends. You take the red pill—you stay in Wonderland, and I show you how deep a  JSON  response goes. Remember: all I’m offering is the truth.

So normally when you sc
