"some online tutorial"?

Correct - in the interactive interpreter, typing the name of an object 
prints its value. You have imported a module and then typed its name.

In both of these, there  is no operator after "pydoc", so what does it mean?

Instead of omitting the result of that, read it!


FWIW, The relevant part based on what I _think_ you're trying to do (as 
you didn't include the URL of your "some online tutorial") is probably 
this part:

"""
DESCRIPTION
     In the Python interpreter, do "from pydoc import help" to provide 
online
     help.  Calling help(thing) on a Python object documents the object.

     Or, at the shell command line outside of Python:

     Run "pydoc <name>" to show documentation on something.
