3.2.4. Organism
Write a Python program that predicts the approximate size of a population of organisms. The application should allow the user to enter the starting number of organisms, the average daily population increase (as a percentage), and the number of days the organisms will be left to multiply. Mathematically, the population for any day \(n > 0\) can be expressed as
(3.1)\[\text{Pop}_{n} = \text{Pop}_{n-1}(1 + \frac{\text{percent increase}}{100})\]
Sample Output
Use the values in Table 3.7 below
to test your program.
Ensure your program’s output matches the provided samples exactly.
This includes all characters, white space, and punctuation. In the
samples, user input is highlighted like
this for clarity, but your program should not highlight user
input in this way.
Case 1 Sample Output
$ python3 organism_login.py
Starting population, in thousands: 2.5
Average daily increase, in percent: 98
Number of days to multiply: 15

Deliverables
Save your finished program as organism_login.py, replacing
login with your Purdue login. Then submit it along with all the
deliverables listed in Table 3.8
below.
