I posted this gist earlier today to check the subtypes that are available in a given feature class.
It’s quite self-explanatory, so I posted it as-is, as a useful code snippet. The subtype codes are returned as keys in the dictionary, while the values are themselves dictionaries containing all the properties of the subtype.
I’m only interested in the description of the subtype, which is why I am printing out the value in the values dictionary at the key ‘Name’. Full description of the function capabilities is here.
On an unrelated note, I can’t get used to the new structure of the online help.
