Perhaps it would help if there were a function

   fprint(f, *args):
     print(file = f, *args)

then the above could be written

   fprint(sys.stderr, 'first line')
   fprint(sys.stderr, 'another line here')
   fprint(sys.stderr, 'and again')

which to me is a lot easier to read, since the file argument
is in a consistent place, making it easier to see that it's
the same from one line to the next.

Also, it enables making the file argument very abbreviated, e.g.

   f = sys.stdout
   fprint(f, 'first line')
   fprint(f, 'another line here')
   fprint(f, 'and again')

Otherwise, the shortest you can get it down to is 'file=f',
which is 6 times as long. It might not seem much, but that's
5 less characters of print arguments that you can fit in
without having to split the line.
