Question

Program #2: Population Increase

Ask the user to give the starting population, a percent yearly increase, and the number of years to display. Then display in a neat table the results. (Note: A percentage value for each year will often not yield a whole number, so we must round to the nearest whole value) You must use a loop of some sort to output the table. Again start and end your programs with friendly messages.

CODE:

print("Let's calculate the population Increase\n") #friendly message at start

population = int(input("Enter the starting population: ")) #Reading the starting population

percent_increase = float(input("Enter yearly increse as percentage: ")) #Reading the yearly increase

num_years = int(input("Enter the number of years to display: ")) #Reading thye number of years to display

print("\nYear Increase Population") #printing table header

year = 1 #Initialize year as 1

while year <= num_years: #Loop for num_years times

    increase = round((population * percent_increase)/100) #calculate the increase in population

    population = population + increase #calculate the total population

   

    print("{:>2d}    {:>5d}     {:>5d}".format(year, increase, population)) #displaying increase and population for each year

   

    year = year + 1 #increment year by 1

   

print("\nGoodbye!!!")   #friendly message at end
