I agree with this point actually. There should be an "iterable" formatting code that looks something like "%[sep]i"

Then "%i" % (myseq,) would be the equivalent of "".join(myseq), only allowing it to be easily embedded inside a larger format string. Some other examples: ("% i" % myseq) => " ".join(myseq) ("%, i" % myseq) => ", ".join(myseq) I see this as being similar to the way that "%.2f" controls the way that a floating point value is displayed. A correction to this - such a formatting operator would need to automatically invoke str on the items in the iterable: ("%i" % (myseq,)) => "".join(map(str, myseq)) ("% i" % (myseq,)) => " ".join(map(str, myseq)) ("%, i" % (myseq,)) => ", ".join(map(str, myseq)) ("%(seq), i" % dict(seq=myseq)) => ", ".join(map(str, myseq))

Hmm, 'i' is already taken. I think I'll use 'j for join' while working on a patch. The full specification of the number formatting operations is impressive, though (this is the first time I've actually read the full description of the string formatting behaviour).

Cheers, Nick.
