The answer to which, in my experience, is to provide consistency with
code that uses a non-trivial format string, such as '"Error: %s" % f',
and/or to suggest to future developers (including me) that this is the
"right" way to make such changes.

Note also that for those who count, "str(f)" is exactly as long
(in keystrokes) as "'%s'%f", making the "just" a matter of opinion.
