Since you can't append to a string, clearly you meant something
different in the second case.  Maybe StringIO?

Python 2.2.2 (#37, Oct 14 2002, 17:02:34) [MSC 32 bit (Intel)] on win32
>>> f = file("somefile", "w")
>>> print >>f, "hello"

>>> import StringIO
>>> s = StringIO.StringIO()
>>> print >>s, "hello"

>>> import sys
>>> out = sys.stdout
>>> print >>out, "hello"
hello

Yes, it is nice that all three methods support the same syntax, 
wouldn't it?  ;-)
