'''
Simulate the growth of a population of nanobots in a Petri dish. It starts 
with an initial population of nanobots which have a specific growth rate 
(e.g., 1.5 per generation). The simulation runs for select number of 
generations, and at each generation, the simulation calculates the new 
population size by multiplying the current population by the growth rate. 
It then prints the current generation number and the population size. When 
the simulation is done, print "Nanobot population simulation complete.".

Implement also the overpopulation condition for the Petri dish: if the 
population reaches 1 milion, all nanobots die. Print a warning at which 
generation this happened.

If the starting population is zero or below, print a warning.

Try to experiment with different initial parameters.
