python之贪吃蛇

废话不多说，直接上代码（确保已经安装 pygame）

"""
food_pos = [random.randrange(1, (SCREEN_WIDTH // GRID_SIZE)) * GRID_SIZE,

GRID_SIZE 是单元格的大小
(SCREEN_WIDTH // GRID_SIZE)) * GRID_SIZE 先对宽度除以单元格取整取得整个宽度的单元格个数

 pygame.draw.rect(screen, GREEN, [pos[0], pos[1], GRID_SIZE, GRID_SIZE])
 画矩形，在屏幕，用什么颜色，在什么位置
 
 snake_body.append(list(snake_pos))
 增加长度
 
 pygame.display.flip()
 刷新屏幕
 
 pygame.draw.rect(screen, WHITE, [food_pos[0], food_pos[1], GRID_SIZE, GRID_SIZE])
 控制食物出现位置
