1. My input is:
    https://www.youtube.com/watch?v=6qNW7yRsqAM
  
   Result is:
    <iframe width="480" height="270" frameborder="0" allowfullscreen="" src="http://www.youtube.com/embed/6qNW7yRsqAM?feature=oembed"></iframe>

  # Code
  def get_description(self):
      providers = micawber.bootstrap_basic()
      description = bleach.clean(self.description)
      description = micawber.parse_text(description, providers)

Result is valid but I did not linkify the content so non embeddable links will not have nofollow/target _blank
