[Tutor] 'pydoc' is not recognized as an internal or external command, ...

[David Hutto]

For what you're looking for you could use:
>>>help(raw_input)

In the python terminal,meaning type python first.

For pydoc on ubuntu in the command line,

 pydoc -p 1234

and then take your
browser to http://localhost:1234, you might need
to select the work offline mode.

On windows IIRC it's about the same. I can check
if you need it.
