this is how your example looks in Python:
def lookup_reference(key):
...
return dict(title=title, author=author, ...)
m = lookup_reference(...)
print "%(title)s was written by %(author)s" % m
(if you fix the bug in your example, and count the characters, you'll find
that my example is a bit shorter)
with enough keys, you can also save typing by using dummy object instead
of a dictionary, and getting rid of the locals in lookup_reference:
def lookup_reference(key):
m = object()
m.title = ... assign directly to return struct members ...
m.author = ...
return m
m = lookup_reference(...)
print "%(title)s was written by %(author)s" % vars(m)
