Hey!
Let me show you, how to code Game OF Life simulation in my favorite language: Python.
At first, I did not fully understand what Game Of Life was all about, from multiple resources - not only wikipedia 😄- I gathered the idea, and step by step, the whole concept was revealed: Evolution!

Please subscribe to my channel, I post a video per week, trying to share what I know without talking, just coding in silence.

The code is below 🙂

``````''This is Game Of Life (Thrones 😄)
simulation coded in Python '''

from random import choice
from turtle import *
import turtle
from freegames import square

cells = {}

# 1 Initialization function
def initialize():
'''Here, we will randomly initialize the cells'''
for x in range( -200, 200, 10):
for y in range( -200, 200, 10):
cells[x,y] = False

for x in range(-50, 50, 10):
for y in range(-50, 50 ,10):
cells[x,y] = choice([True, False])

# 2 Step function
def step():
'''Here, we will compute one step in the game of life.'''
neighbors = {}

for x in range(-190, 190, 10):
for y in range(-190, 190, 10):
count = -cells[x,y]
for h in [-10, 0, 10]:
for v in [-10, 0, 10]:
count += cells[ x + h, y + v ]
neighbors[x,y] = count

for cell, count in neighbors.items():
if cells[cell]:
if count < 2 or count > 3:
cells[cell] = False
elif count == 3:
cells[cell] = True

# 3 The drawing function
def draw():
'''Here, we are going to draw all the green squares, i choose green to match the channel's theme 😄'''
step()
clear()
for (x,y), alive in cells.items():
color = 'green' if alive else 'black'
square(x,y,10,color)
update()
ontimer(draw, 100)

'''Setting up the turtle window'''
turtle.title("Game of life")
setup(420, 420, 370, 0)
hideturtle()
tracer(False)
initialize()
draw()
done()
