True, just wanted to know whether there is such a tool.

I personally like the %-notation a lot, mainly because it's more
or less the same as in C.

%i, %s and %r are by far the most used format characters in our code base.
Determining the position index and writing {0!s} or {0!r} instead
(which requires quite a finger dance on a German keyboard) doesn't
make .format() really attractive, IMHO.

Perhaps you're right and it's better to wait a few rounds of
refinements of .format() before jumping on that train :-)
