I apologize if this has already been mentioned in this thread, but are
you aware of "d.keys()" and "d.values"?
>>> d = {}
>>> d['do'] = 'a deer, a female deer'
>>> d['re'] = 'a drop of golden sunshine'
>>> d['mi'] = 'a name I call myself'
>>> d['fa'] = 'a long, long way to run'
>>> d.keys()
['fa', 'mi', 'do', 're']
>>> d.values()
['a long, long way to run', 'a name I call myself', 'a deer, a female deer', 'a drop of golden sunshine']
>>>
