I have some data that looks like the attached pic. There's got to be an easy way to get a total area for each USE_CATEGORY and put the totals into a list or dictionary. Not sure if I need to maintain which total relates to which USE_CATEGORY. I don't need it for the current calculation I want to do, but may be worthwhile if I want to write it out to some external format later.
Thanks for any help/pointers.
