def get_packages_info(packages): # Tu código aquí 👈 weight = [package[1] for package in packages] tuple_destinations = tuple(package[2] for package in packages) destinations = {destino: tuple_destinations.count(destino) for destino in tuple_destinations} total_weight = round(sum(weight),2) return {"total_weight": total_weight, "destinations": destinations }
creo que tu código es el mejor que he visto
Simple y elegante, perfecto.

Mi solución al reto:

jajaja no entendi que te iban a dar paises al azar y no solo iban a ser los 3 que vienen en la guia, este codigo solo sirve para esos 3 paises

Hola a todos, comparto mi solucion.

Como de costumbre funciona en pycharm pero no en playground
aqui mi solucion:
def get_packages_info(pakages): destination = list(set(pack[2] for pack in packages)) total_weight = round(sum([pack[1] for pack in packages]),3) total_destination = [{destination[i]: sum(pack.count(destination[i]) for pack in packages)} for i in range(len(destination))] return f"total_weight: {total_weight}, destinations: {total_destination}"
Hola, el error es porque la respuesta que has definido es un string. Cuando lo que debes regresar es un dictionary. Puedes cambiarlo sustituyendo el return por: return {"total_weight": total_weight, "destinations": total_destination}
después de resolver el ejercicio y ver las respuestas de muchos, mi recomendación es que no abusen de los bucles for dado que esto aumenta la complejidad.
