Well, hopefully I understood you correctly, but if we assume that the dataset
is a simple list you can iterate over it as thus:

for subject in dataset:
    do_geoprocessing(subject)

Dictionaries and other datatypes have similar means to construct an iterator.

Is this a bit what you want to achieve?
