There is no overview of Aruban (cities and) villages on Wikidata
I would just do this with one of the existing great data import tools for Wikidata! No need to write a script in my opinion? Unless learning to write such a script is a goal in itself...?
Maybe @Pintoch would be willing to teach you OpenRefine, specifically with this dataset?
Unable to import data since there is not a source available right now to find the correct data that has high accuracy. The challenge with Aruba is that it consists of just a few cities. In these cities there are a lot of neighbourhoods. That goal is to find data that distinguishes the cities/towns from neighbourhoods.
Action point for the future:
Find a data base that has the cities and towns of Aruba and does not contain the neighbourhoods.
