Started looking at pygame, yesterday. Big problem; how to quit.
The window for the little snake game I found just would not close.
Adding pygame.quit() at the end allows it to close, but only from the
PyCharm page.
import pygame
import random
pygame.init()
green = (0, 255, 0)
blue = (50, 153, 213)
dis_width = 400
dis_height = 400
dis = pygame.display.set_mode((dis_width, dis_height))
clock = pygame.time.Clock()
def run():
x1 = dis_width / 2
y1 = dis_height / 2
dir = [0, 0]
snake_list = []
snake_len = 1
foodx = 30
foody = 30
while True:
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
dir = [-10, 0]
elif event.key == pygame.K_RIGHT:
dir = [10, 0]
elif event.key == pygame.K_UP:
dir = [0, -10]
elif event.key == pygame.K_DOWN:
dir = [0, 10]
x1 += dir[0]
y1 += dir[1]
dis.fill(blue)
pygame.draw.rect(dis, green, [foodx, foody, 10, 10])
snake_list.append([x1, y1])
if len(snake_list) > snake_len:
del snake_list[0]
if ([x1, y1] in snake_list[:-1]):
run()
if (x1 >= dis_width or x1 < 0 or y1 >= dis_height or y1 < 0):
run()
for x in snake_list:
pygame.draw.rect(dis, green, [x[0], x[1], 10, 10])
if x1 == foodx and y1 == foody:
foodx = round(random.randrange(0, dis_width - 10) / 10.0) * 10.0
foody = round(random.randrange(0, dis_height - 10) / 10.0) * 10.0
snake_len += 1
pygame.display.update()
clock.tick(10)
run()
pygame.quit()
The Tech with Tim intro to Pygame starts with precisely how-to quit.

Got the tutorial code running. Only change I made was replacing the RCRTL key
with SLASH because that is a key I don't have on my smaller computer... As for enabling
the sound effects, these are loud and rather dramatic... All in all, a classic game, and helpfully
explained.
