No, that would be cities['_find'] = find_city() When you use cities['_find'] = find_city the value of the extra item is _the function find_city itself_. And thus later city_found = cities['_find'](cities,state) will be equivalent to city_found = find_city(cities,state) -- André Engels, andreeng...@gmail.com _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
