The built-in function format():

http://docs.python.org/3.3/library/functions.html?highlight=format%20builtin#format

The first parameter is a single object, NOT a sequence.  One object, one
format.  If you want more generality, use the str.format() method:

http://docs.python.org/3.3/library/stdtypes.html?highlight=format#str.format

where you can supply a list or a dictionary of multiple items to be
formatted into a single string.  That's the one where you supply the
curly braces.
