Since a program author can easily do so, as has been posted more than once
over the years, the question was real.  In fact, the addition of '>>ofile'
to print statements was intended to make such redirection less common.

I don't know the ramification of the distinction, expecially across
platforms, well enough to answer.  I can only reiterate my suggestion,
given Python as it is today and will remain for some time, that you print
to 'ofile' with default ofile == sys.stdout but with command line or
interactive redirection.
