If you're using an object namespace, then you can just do this:

print("{o.solo} was captured by {o.jabba}".format(o=self))

That looks a lot cleaner to me than passing in **vars(self).  For
locals(), I can see the appeal, but I tend to avoid it because it has
the same icky feeling as doing an import *.
