You mean like this?

>>> var = 'hello'
>>> print var 'world'
  File "<stdin>", line 1
    print var 'world'
                    ^
SyntaxError: invalid syntax

The above is to demonstrate that you neet to use apostrophes. *hoping
people think that was a deliberate mistake*
>>> print var
hello
>>> print var, "world"
hello world
>>> var2 = "I'm Joal"
>>> print var, 'world', var2
hello world I'm Joal

Also, if var can be cooerced into a string, you can print it as well.
>>> var = 1
>>> str(var)
'1'
>>> print var2, "I'm no.", var, ".... Not!!!"
I'm Joal I'm no. 1 .... Not!!!

Additionally, others have pointed out the use of the % operator.

I've heard that Google is built on python. You made a comment later on
about serverlets. As somebody pointed out, you can drop Jython into
serverlets, but I think Zope also has a server philosophy. I don't
actually know what Zope is for - something about a Network Application
Server or something. The Zope fanatics will straighten me out but will
also point out that it has a steep learning curve.
