Write a loop that prints each country's population in country_pop. Sample output with input: 'China:1365830000,India:1247220000, United States:318463000,Indonesia:25216480 0': United States has 318463000 people. India has 1247220000 people.

Hi there! This question is good to check your understanding of loops. To illustrate, I have implemented the answer in Python and explained it below.

Explanation:

Assuming user input for the country and population list as provided in the question, we can write the python script "country_pop.py" and run it from the command line. First we prompt user for the input, after which we split the country-population list which is separated or delimited with a comma into an array of country-population list. We then create a hash of country and its corresponding population by further splitting the country-population combo into a hash, and finally, printing the resultant hash as the output.    

country_pop.py

def add_country_pop(country, population):

 countrypop_hash[country]=population

countrypop_hash = {}

input_string = input("Enter country population list: ")

print(input_string)

countrypop_array = input_string.split(",")

for country in countrypop_array:

 country_pop = country.split(':')

 pop_country = country_pop[0]

 population = country_pop[1]

 add_country_pop(pop_country, population)

 print(country + ' has ' + population + ' people')

Output

> country_pop.py

Enter country population list: China:1365830000,India:1247220000,United States:318463000,Indonesia:252164800

China:1365830000,India:1247220000,United States:318463000,Indonesia:252164800

China:1365830000 has 1365830000 people

India:1247220000 has 1247220000 people

United States:318463000 has 318463000 people

Indonesia:252164800 has 252164800 people
