Me gustó el Juego de la vida de Conway y comencé a intentar escribirlo en Python. En este momento aún no he escrito ningún código para los bordes del programa, así que solo estoy pidiendo ayuda con lo que tengo ahora. Parece que tengo problemas al inicializar una formación "intermitente". En lugar de oscilar como debería, parece convertirse en un cubo.

#File: gameoflife.py
#Description: This is a basic "life" simulation that follows three distinct rules:
#1.Any live cell with fewer than two live neighbours dies
#2.Any live cell with two or three live neighbours lives
#3.Any live cell with more than three live neighbours dies
#4.Any dead cell with exactly three live neighbours becomes a live cell
#A neighbor is deemed as any cell directly horizantal/vertical/diagonal
#meaning there are 9 neighbors to a cell at any time
