So I am trying to make a simple Conway's game of life in PyCharm, and I can only get a a bunch outputs and not a video like stream in the output console. Is there a command that will let me clear the output every loop in the program. I have already tried the "sys" commands, and the ANSI escape keys (I hope I spelled that right). Nothing seems to be working! I am using Python 3.
I would like to clear the console on the first print statement in the while loop. If that helps.
import copy
import random
import time
WIDTH = 60
HEIGHT = 10
nextCells = []
for x in range(WIDTH):
column = []
for y in range(HEIGHT):
if random.randint(0, 1) == 0:
column.append('#')
else:
column.append(' ')
nextCells.append(column)
while True:
# print('\n\n\n\n')
currentCells = copy.deepcopy(nextCells)
for y in range(HEIGHT):
for x in range(WIDTH):
print(currentCells[x][y], end='')
print()
On the command prompt (not PyCharm console), try the colorama
library to move the cursor back up and print the next iteration over the current iteration (colorama
makes ANSI control codes compatible with Windows):
(colorama
can be installed via pip install colorama
)
import copy
import random
import time
import colorama
colorama.init()
WIDTH = 60
HEIGHT = 10
nextCells = []
for x in range(WIDTH):
column = []
for y in range(HEIGHT):
if random.randint(0, 1) == 0:
column.append('#')
else:
column.append(' ')
nextCells.append(column)
while True:
#print('\n\n\n\n')
currentCells = copy.deepcopy(nextCells)
for y in range(HEIGHT):
for x in range(WIDTH):
print(currentCells[x][y], end='')
print()
for x in range(WIDTH):
for y in range(HEIGHT):
leftCoord = (x - 1) % WIDTH
rightCoord = (x + 1) % WIDTH
aboveCoord = (y - 1) % HEIGHT
belowCoord = (y + 1) % HEIGHT
numNeighbors = 0
if currentCells[leftCoord][aboveCoord] == '#':
numNeighbors += 1
if currentCells[x][aboveCoord] == '#':
numNeighbors += 1
if currentCells[rightCoord][aboveCoord] == '#':
numNeighbors += 1
if currentCells[leftCoord][y] == '#':
numNeighbors += 1
if currentCells[rightCoord][y] == '#':
numNeighbors += 1
if currentCells[leftCoord][belowCoord] == '#':
numNeighbors += 1
if currentCells[x][belowCoord] == '#':
numNeighbors += 1
if currentCells[rightCoord][belowCoord] == '#':
numNeighbors += 1
if currentCells[x][y] == '#' and (numNeighbors == 2 or numNeighbors == 3):
nextCells[x][y] = '#'
elif currentCells[x][y] == ' ' and numNeighbors == 3:
nextCells[x][y] = '#'
else:
nextCells[x][y] = ' '
# Here we move the cursor back up:
print(f'\033[{HEIGHT+1}A')
time.sleep(1)
