Question:
Please look at this code, I need this code to print" Please enter a death_rate that is less than the birthrate" when the user enters a death_rate that is lower than birth rate. At present, the program is left hanging if this scenario happens (there is an *). Attached is the picture.
# Define a function to calculate the number of years needed to reach the target population.
def calculate_years(starting_population, birthrate, death_rate, target_population):
# Initialize current_population and years to keep track of the population and years passed.
current_population = starting_population
years = 0
# Use a while loop to simulate population growth until the target is reached.
while current_population < target_population:
# Calculate the new population after one year, taking into account birth and death rates.
current_population += (birthrate - death_rate) * current_population
# Increment the year count.
years += 1
# Return the number of years needed to reach the target population.
return years
# Input values from the user.
starting_population = int(input("Enter the starting population: "))
birthrate = float(input("Enter the annual birthrate (as a decimal): "))
death_rate = float(input("Enter the annual death rate (as a decimal): "))
target_population = int(input("Enter the target population: "))
# Call the calculate_years function to get the result.
years_needed = calculate_years(starting_population, birthrate, death_rate, target_population)
# Display the result to the user.
print(f"It will take {years_needed} years to reach a population of {target_population}.")
