Python Program:

class City:

    __totalPopulation = 0

    def__init__(self, name, population):

        self.name = name

        self.population population

        City._City__totalPopulation+=population

    def str (self): 

        return self.name+":"+str(self.population)

N= int(input())

cities = []

for ctr in range (N):

    name, population input().split() 

    cities.append(City (name, int(population)))

print(City. _City__totalPopulation)

for city in cities:

    print(city)
