output was going nicely as I input text from my 'Getting Started with

lxml not being installed, things went right, because I had already installed
it, re:

Then on bottom of page 20 it says 'we should install the required parsers using
easy-install,pip or setup.py install' but as I can't get the downloads of html
or html5 parsers, text code halfway down returns statutory response regarding
requisite parser needing to be installed, re:

ValueError: Couldn't find a tree builder with the features you requested:
html5lib. Do you need to install a parser library?
Have you tried this from the command prompt?
pip install html5lib
And please do something about the extra newlines and single lined
paragraphs above, there's no need for it all.
