Login and get codingIn this Bite you are presented with a list of surnames, names, and countries. These 3 fields are in a multiline string, separated by a comma.
Code
group_names_by_country
, looping through the list, returning acollections.defaultdict
where the keys are countries and the values arelist
s of concatenated names and surnames. The order of the keys (countries) and the value lists (names) does not matter.Here is an example of a possible input to your function:
data = """last_name,first_name,country_code Watsham,Husain,ID Harrold,Alphonso,BR Apdell,Margo,CN Tomblings,Deerdre,RU Wasielewski,Sula,ID Jeffry,Rudolph,TD Brenston,Luke,SE Parrett,Ines,CN Braunle,Kermit,PL Halbard,Davie,CN"""... and the output your function should return:
defaultdict(<class 'list'>, {'BR': ['Alphonso Harrold'], 'CN': ['Margo Apdell', 'Ines Parrett', 'Davie Halbard'], 'ID': ['Husain Watsham', 'Sula Wasielewski'], 'PL': ['Kermit Braunle'], 'RU': ['Deerdre Tomblings'], 'SE': ['Luke Brenston'], 'TD': ['Rudolph Jeffry']})Good luck and keep calm and code in Python!
