Installing Parsers/Tree Builders to, and accessing these packages from Python2.7

[Simon Evans]

I input 'pip install html5lib' to the Python 2.7 console and got :

>>> pip install html5lib
  File "<stdin>", line 1
    pip install html5lib
              ^
SyntaxError: invalid syntax
>>>

I am not sure what you mean about 'single line paragraphs'. I put my text 

into double line spacing in my last missive, I left the code input/ output 

in single line spacing as that is how it reads from the console, after all 

who am I to alter it? Regarding 'context' if you are referring to the text 

I am using, it is from 'Getting Started in Beautiful Soup' by Vineeth G.

Nair. 

For what its worth some of the subsequent code in the book runs, but not 

all, and I think this may be due to the parser installation factor, and I 

wanted to work through the book (112 pages) without any errors being 

returned.
