def fnKey(dic, value):
return [k if value == v else pass for k, v in dic.iteritems()]
can anyone tell me why this doesn't work?
i'm trying to return the key for a known value from a dictionary

Why so complicated? You could simply do like:
>>> d = {1:1, 2:4, 3:8, 4:16}
>>> print[k for k in d if d[k]==8]
