the print statement is more convenient. Maybe a print builtin wouldn't kill me. In that case I'd want both output redirection and newline suppression though. I guess you'd have to use a keyword arg to specify an alternate stream. Perhaps if the last non-keyword argument was exactly one space, the newline could be suppressed, e.g.:

print("foo", "bar", "baz", " ", stream=sys.stderr)

I think, instead, the stream API should grow a "print" method (or whatever it ends up getting called). The example would then look like:

sys.stderr.print("foo", "bar", "baz", " ")

It would probably be nice to provide a FileMixin object too. (Actually, this would be nice now, so that if I implement read(), I don't have to implement readline(), readlines(), etc.) The FileMixin object would make it easy for user-defined file-like objects to also support the print() method:

class FileMixin(object):
    """Adds the file methods.

    Requires:
        read()
        write()

    Adds:
        __iter__()
        next()
        readline()
        readlines()
        writelines()
        print() # or whatever it gets called
    """
    ...
