Thanks for the tutorial! Love the music in the background; it's tech but calming at the same time and doesn't distract or annoy from the actual content.

Showing the whole coding process was great. Thanks for this tutorial!

Python returned an error: No module named 'grid'

Where do I go from there? How do I solve this?

[disdis]

Wow that's what I was looking for

[claireatati]

where did you get your soundtrack, I really like listening to it while working

Conway() got an unexpected keyword argument 'surface'

Hello, hopefully someone sees this, but mine is static. Does it require a mouse click to get cells moving? I did this on a tablet so I’m not using a mouse.

I don't know if you will see this, but is there a reason for just checking the 4 directly adjacent tiles and not the 4 diagonal tiles as well as those also are counted when getting the total amount of live neighbors?
EDIT: Great Video btw!

os comparto el código que encontré en el libro "automate the boring stuff with python"
# Conway's Game of Life
import random, time, copy
WIDTH = 60
HEIGHT = 20

# Create a list of list for the cells:
nextCells = []
for x in range(WIDTH):
column = [] # Create a new column.
for y in range(HEIGHT):
if random.randint(0, 1) == 0:
column.append('#') # Add a living cell.
else:
column.append(' ') # Add a dead cell.
nextCells.append(column) # nextCells is a list of column lists.

while True: # Main program loop.
print('\n\n\n\n\n') # Separate each step with newlines.
currentCells = copy.deepcopy(nextCells)

# Print currentCells on the screen:
for y in range(HEIGHT):
for x in range(WIDTH):
print(currentCells[x][y], end='') # Print the # or space.
print() # Print a newline at the end of the row.

# Calculate the next step's cells based on current step's cells:
for x in range(WIDTH):
for y in range(HEIGHT):
# Get neighboring coordinates:
# `% WIDTH` ensures leftCoord is always between 0 and WIDTH - 1
leftCoord = (x - 1) % WIDTH
rightCoord = (x + 1) % WIDTH
aboveCoord = (y - 1) % HEIGHT
belowCoord = (y + 1) % HEIGHT

# Count number of living neighbors:
numNeighbors = 0
if == '#':
numNeighbors += 1 # Top-left neighbor is alive.
if currentCells[x][aboveCoord] == '#':
numNeighbors += 1 # Top neighbor is alive.
if == '#':
numNeighbors += 1 # Top-right neighbor is alive.
if currentCells[leftCoord][y] == '#':
numNeighbors += 1 # Left neighbor is alive.
if currentCells[rightCoord][y] == '#':
numNeighbors += 1 # Right neighbor is alive.
if == '#':
numNeighbors += 1 # Bottom-left neighbor is alive.
if currentCells[x][belowCoord] == '#':
numNeighbors += 1 # Bottom neighbor is alive.
if == '#':
numNeighbors += 1 # Bottom-right neighbor is alive.

# Set cell based on Conway's Game of Life rules:
if currentCells[x][y] == '#' and (numNeighbors == 2 or
numNeighbors == 3):
# Living cells with 2 or 3 neighbors stay alive:
nextCells[x][y] = '#'
elif currentCells[x][y] == ' ' and numNeighbors == 3:
# Dead cells with 3 neighbors become alive:
nextCells[x][y] = '#'
else:
# Everything else dies or stays dead:
nextCells[x][y] = ' '
time.sleep(1) # Add a 1-second pause to reduce flickering.

Ohk that was crazy...

Could you please increase fount size

[alimartinzynda]

im sorry, this library you used: "grid", can you give me please some info about it? i couldn't find it. Thanks :)

Hi...i have implemented Conway game of life in Python. It works very well if you draw your initial configuration "by hand" using your mouse. Now I want to implement some famous initial configuration (for example a gun or an oscillator) but I don't want to copy it using the mouse...I'm looking for a way to import the grid of a particoular configuration...do you have any idea? Thank you

[priyanshsoni]

bro m getting a list index out of range when we assign the colors to the cells as in if self.grid_array[i][j] == 1 then we do pygame.draw.rect()

Unoptimized code, very slow to iterate over the 2D array point by point.
