In this Bite you are going to parse some Latin American countries in
xml, specifically the output of api.worldbank.org/V2/country?region=LCN which we stored here. It's already saved for you in the
get_income_distributionby reading in this file, parsing its XML and returning a
dictof keys = wb:incomeLevel and values =
lists of country names (wb:name).
defaultdictis a convenient data structure to use here. See also the tests for the expected return.
Good luck and code more Python!
