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" % (my_seq,)) => "".join(map(str, my_seq)) ("% i" % (my_seq,)) => " ".join(map(str, my_seq)) ("%, i" % (my_seq,)) => ", ".join(map(str, my_seq)) ("%(seq), i" % dict(seq=my_seq)) => ", ".join(map(str, my_seq))

Cheers, Nick.
