>>> class Translate:
...     def __init__(self, dest):
...             self.dest = dest
...     def write(self, s):
...             self.dest.write(s.replace("\n", "\r\n"))
...     def __getattr__(self, name):
...             return getattr(self.dest, name)
...
>>> f = Translate(file("tmp.txt", "w"))
>>> print >> f, "so what"
>>> print >> f, "will this print?"
>>> f.close()
>>> file("tmp.txt").read()
'so what\r\nwill this print?\r\n'

Simple enough?
