A local biologist needs a program to predict population growth. The inputs would be:

The initial number of organisms

The rate of growth (a real number greater than 1)

The number of hours it takes to achieve this rate

A number of hours during which the population grows

For example, one might start with a population of 500 organisms, a growth rate of 2, and a growth period to achieve this rate of 6 hours. Assuming that none of the organisms die, this would imply that this population would double in size every 6 hours. Thus, after allowing 6 hours for growth, we would have 1000 organisms, and after 12 hours, we would have 2000 organisms.

Write a program that takes these inputs and displays a prediction of the total population.

An example of the program input and output is shown below:

Enter the initial number of organisms: 10 Enter the rate of growth [a real number > 0]: 2 Enter the number of hours to achieve the rate of growth: 2 Enter the total hours of growth: 6 The total population is 80 

This is the code I have so far.

def predict_population(): import math sp = input("Enter the initial number of organism: ") r = input("Enter the rate of growth [a real number > 0]: ") while r > 1 or r < 0: print ("Invalid population growth rate.") r = input("Enter the number of hours to achieve the rate of growth: ") t = input("Enter the total hours of growth: ")

for i in range(t): tp = sp * math.exp(r*t) print ("The population after",t,"years will be",tp)

predict_population()
