Answer:
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
