Question

language: python

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

1. The initial number of organisms, as an int
2. The rate of growth (a real number greater than 1), as a float
3. The number of hours it takes to achieve this rate, as an int
4. A number of hours during which the population grows, as an int

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 > 1]: 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

also make sure it test for these cases

Test Case 1

Test for 100 organisms with growth rate of 5 over 2 hrs over 25 hrs total

Test Case 2

Test for 10 organisms with growth rate of 2 over 2 hrs over 6 hrs total

Test Case 3

Test for 0 organisms with growth rate of 5 over 1 hr over 6 hrs total

Test Case 4

Test for 7 organisms with growth rate of 7 over 7 hrs over 7 hrs total

Answer 1

code:

output :

raw_code :

#taking inputs
initial = int(input('Enter the initial number of organisms : '))
rate = float(input('Enter the rate of growth[a real number >1] :'))
hours = int(input('Enter the number of hours to achieve the rate of growth :'))
total = int(input('Enter the total hours of growth :'))

population = initial

#calculating population growth
for i in range(hours,total+1,hours):
population *= rate

#prinint output
print('The total population is ',population)
