This question may expose my ignorance on programming but I'm curious about how people are using different python data structures within Arcpy.
This page lists the data structures in Python. I understand how lists can be implemented in GIS (list of feature classes, list of feature types, list of data frames, etc). I understand how sets can be used as well (to remove duplicates). How are people implementing tuples, dictionaries, and other data structures within Arcpy? Also, are there other examples of lists and sets which I haven't listed?
Furthermore, no doubt, people are creating custom classes in Arcpy. Under what circumstances and situations do you require these? Can you provide examples? Is anyone creating custom classes which inherit from the built-in arcpy classes?
I don't require answers to all of these questions, I'm just curious how people are using Python in GIS and what workflows require these customizations.
Thanks in advance.
