I'd probably put the values in a dictionary, using your
labels as keys. Although if you've actually got two arrays
(which your labels seem to suggest) using two lists might
be a better idea.

In either case, it should be easy to construct a loop to unpack
the string into a dictionary or list. You could do the same thing
with the instance variables of a class, but then you'd have to
insert the variables with setattr().
