Python optparse Values Instance

How can I take the opt result of

opt, args = parser.parse_args()

and place it in a dict? Python calls opt a “Values Instance” and I can’t find any way to turn a Values Instance into a list or dict. One can’t copy items from opt in this way,

for i in opt:
 myDict[i] = opt[i]

instead, its a clumsy,

myDict[parm1] = opt.parm1
myDict[parm2] = opt.parm2

which implies that every time I add an option, I have to update this code as well; there should be a way to let this take care of itself.
