Consider a dict like
mydict = { \'Apple\': {\'American\':\'16\', \'Mexican\':10, \'Chinese\':5}, \'Grapes\':{\'Arabian\':\'25\',\'Indian\':\'20\'} }
You can't rely on order on dictionaries. But you may try this:
dict['Apple'].items()[0][0]
If you want the order to be preserved you may want to use this: http://www.python.org/dev/peps/pep-0372/#ordered-dict-api
