That's a lot older than Python 3. Here's the example from the 2.3
docs: http://docs.python.org/release/2.3/lib/typesseq-strings.html
Python 3 added a different syntax for string formatting, using .NET's
formatting syntax instead of C's.
"{scheme}://{host}:{port}/{route}#{fragment}".format(locals())
