Here, you want `return "Hello there world!"` , instead of `print ...`.

   If you're going to do `"""+helloWorld()+"""` later on,
you're counting on the value returned by helloWorld .. not
on any I/O that gets done inside helloWorld.  As you coded
it, without any return statement, helloWorld actually
returns a reference to the object named 'None', and the
resulting error shuts down your program before you can see
the entire printout.

   For an interesting sideline, add a statement
`return " :-) "` after `print "Hello there world!"` .
The result will show you the order things are actually
getting done in.  You may need to view source in your
browser to see everything .. it depends.
