This might be of use:
return """foo: {foo}
bar: {bar}
baz: {baz}""".format(**self.__dict__)
You're repeating yourself a bit, but this allows the labels to differ
from the format tags. If you're certain that you don't need that
flexibility, you could generate the format string dynamically:
return "\n".join(x+": {"+x+"}" for x in
("foo","bar","baz")).format(**self.__dict__)
That scales more nicely as the number of elements desired increases
(while still being 100% explicit - the presence and order of elements
is governed by the tuple), but is a bit inflexible and complicated.
I'd be inclined toward the triple-quoted-string one.
