[Tutor] Help with vars()

[Charlie Clark]

I'd like to use vars() in together with a database command (Marc André 
Lemburg's mxODBC) but seem to have missed something.

articles = {'sternzeichen': 'Wassermann', 'text': 'Es wird besser', 
'headline': 'Horoskop f\xc3\xbcr Peter'}

when I use
insert = "%headline, %text, %sternzeichen" %vars(articles)

I get a TypeError:
TypeError: vars() argument must have __dict__ attribute

but articles is a dictionary... what screamingly obvious thing am I missing?
