Inspired by Conway's Game of Life
Probably the largest single program I've made so far (800 lines, give or take)
Originally created for use as a small science fair project. It just takes the following ecosystem and simulates it over generations (you can choose how many ecosystems to generate at a time, or enter 0 to end program. Can generate roughly 15 generations in one shot before lagging).
Ecosystem: grass, grasshopper, rabbit, mouse, snake, kookaburra, eagle
The initial generation is based off of random numbers, so you will get a different population every time you open up the program. The basis of whether an animal survives, dies, and/or how many it can reproduce is set with values.
Keep in mind I had no intention of making an efficient program, as this was just for fun :)
*I reccommend running the program in some live console, such as the one on repl.it
