There is of course:

print "Hello", name
print "Hello", name[1]

But that is probably not what you ask for. There is a thread about
extending the print statement right now at the python-dev mailing list:
http://www.python.org/pipermail/python-dev/2000-July/thread.html

Part of this thread deals with what you are looking for.
You may want to read the whole thread, but a good point to start
is Tim's first post in that subthread:

As far as I have understood matters, the $name $(name[1]) syntax
woul be able to do what you want. But then I have not really
followed that thread closely.

P.S.: To python-dev: Wouldn't it be better to discuss this
                     on python-list (or pep-dev<wink>)?
