Population.py
Problem
You get bored one day and want to create your own species. You want to be able to set a growth rate for your creation - how fast per day they will grow. You decide that your species will start at a population of 10,000. You know that you want to set the growth rate between 0.5 and 1.5, inclusive.
If your population would grow, your program should tell the user how many whole days it will take for the population to double in size, or hit 20,000 or more.
If your population would stay stagnant, your program should print out a message notifying the user of that.
If your population would decay, your program should tell the user how long it take for the population to die, for our purposes, reach a value of less than 1.
Example
> Growth rate: 1.2
> Your population is going to grow twofold in...
> 4 days
So, if our growth rate is 1.2, initially, on day 0, our population is 10,000. On day 1, we multiply this by 1.2, so our population is 12,000. On day 2, we multiply again by 1.2, so our population is 14,400. On day 3, our population is 17,280. On day 4, our population is 20,736. Since on day 4 our population is greater than 20,000, we output "4 days".
Testing
Your program should output the following. Test with your own input and see if the program works as intended!
> Growth rate: 0.8
> Your population will die in...
> 42 days
> Growth rate: 1.1
> Your population is going to grow twofold in...
> 8 days
> Growth rate: 1
> Your population will stay stagnant!
> Growth rate: 0.4
> Invalid input.
Submission
Save your work as "lastname_population.py" and submit on Google Classroom with your other two programs.
