Well, according to the python beginners book; "Dive Into Python" [1], string formatting is less error prone as it also does type coercion whereas string concatenation only works when all objects are already strings. When it's possible that a user will be passing in parts of the concatenation, I'd rather be using formatting for that reason alone.
I had thought that I read from that same source that formatting is faster than concatenation (and that's why I checked there before responding), but I don't see that mentioned. Not sure where I got that idea or if its even true.
