Game of Life (neighbors)

[ThomasL]

Using above neighbor calculation a simple Game of Life
can be done like this:

import numpy as np
from scipy.signal import convolve2d
import os
import time

SIZE = 30, 30

def show(table):
	star = table * ord('*')
	blank = (table != 1) * ord(' ')
	field = star + blank
	for row in field:
		print(''.join(chr(char) for char in row))

kernel = np.array([[1,1,1],[1,0,1],[1,1,1]]).astype(np.uint8)
table = np.random.randint(0, 2, size=SIZE).astype(np.uint8)
os.system('cls')
print(table)

for i in range(100):
	next_table = table.copy()
	neighbors = convolve2d(table, kernel, 'same')
	next_table[neighbors < 2] = 0
	next_table[neighbors > 3] = 0
	next_table[(neighbors == 3) & (table == 0)] = 1
	table = next_table
	os.system('cls')
	show(table)
	time.sleep(.050)
