Actually, the print statement doesn't "automatically insert"
the trailing space at that time -- it just sets the .softspace
attribute on sys.stdout to 1.  The NEXT forthcoming print
will test that attribute and start with the space if needed.

In other words, you CAN 'remove the trailing space' while
using the print statement rather than the write function,
if you wish...:

    for i in hugelist:
        dofoobar(i)
        print f(i),
        sys.stdout.softspace=0
        dobarbaz(u)

Using sys.stdout.write(str(f(i))) may indeed be better, but
I did want to point out that print is subtler than one might
think... sometimes that can come in handy.
