Question

Please use python with a for loop to explain. Thanks in advance for the help! ^^

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

1. The initial number of organisms
2. The rate of growth (a real number greater than 1)
3. The number of hours it takes to achieve this rate
4. 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

Answer 1

Python code:

organisms = int(input("Enter the initial number of organisms: "))
rate = int(input("Enter the rate of growth(a real number >0): "))
hours = int(input("Enter the number of hours to achieve the rate of growth:"))
totalhours = int(input("Enter the total hours of growth:"))

finalorganisms =organisms

for i in range(0,totalhours,hours):
    finalorganisms*=rate
  
print("The total population is ",finalorganisms)
