写个Python贪吃蛇的游戏程序

### 回答1：

可以！这里有一个简单的Python贪吃蛇游戏程序的例子： import random
import curses

s = curses.initscr()
curses.curs_set(0)
sh, sw = s.getmaxyx()
w = curses.newwin(sh, sw, 0, 0)
w.keypad(1)
w.timeout(100)

snk_x = sw/4
snk_y = sh/2
snake = [
[snk_y, snk_x],
[snk_y, snk_x-1],
[snk_y, snk_x-2]
]

food = [sh/2, sw/2]
w.addch(food[0], food[1], curses.ACS_PI)

key = curses.KEY_RIGHT

while True:
next_key = w.getch()
key = key if next_key == -1 else next_key

if snake[0][0] in [0, sh] or snake[0][1] in [0, sw] or snake[0] in snake[1:]:
curses.endwin()
quit()

new_head = [snake[0][0], snake[0][1]]

if key == curses.KEY_DOWN:
new_head[0] += 1
if key == curses.KEY_UP:
new_head[0] -= 1
if key == curses.KEY_LEFT:
new_head[1] -= 1
if key == curses.KEY_RIGHT:
new_head[1] += 1

snake.insert(0, new_head)

if snake[0] == food:
food = None
while food is None:
nf = [
random.randint(1, sh-1),
random.randint(1, sw-1)
]
food = nf if nf not in snake else None
w.addch(food[0], food[1], curses.ACS_PI)
else:
tail = snake.pop()
w.addch(tail[0], tail[1], ' ')

w.addch(snake[0][0], snake[0][1], curses.ACS_CKBOARD)

Python贪吃蛇游戏程序的实现是一个很有趣的项目。下面是一种可能的实现方式：

import pygame
import time

# 初始化游戏
pygame.init()

# 设置游戏窗口大小和标题
width, height = 800, 600
window = pygame.display.set_mode((width, height))
pygame.display.set_caption("贪吃蛇游戏")

# 定义颜色
BLACK = (0, 0, 0)
GREEN = (0, 255, 0)
WHITE = (255, 255, 255)

# 定义蛇的初始位置和大小
snake_pos = [[100, 50], [90, 50], [80, 50]]
snake_size = 10

# 定义食物的初始位置和大小
food_pos = [random.randrange(1, (width//10)) * 10, random.randrange(1, (height//10)) * 10]
food_size = 10

# 定义分数
score = 0

# 定义蛇的移动速度
snake_speed = 15
snake_direction = "RIGHT"
change_to = snake_direction

# 控制游戏是否结束变量
game_over = False

# 游戏主循环
while not game_over:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RIGHT:
                change_to = "RIGHT"
            if event.key == pygame.K_UP:
                change_to = "UP"
            if event.key == pygame.K_DOWN:
                change_to = "DOWN"
            if event.key == pygame.K_LEFT:
                change_to = "LEFT"
    
    # 更新蛇的方向
    if change_to == "RIGHT" and snake_direction != "LEFT":
        snake_direction = "RIGHT"
    if change_to == "UP" and snake_direction != "DOWN":
        snake_direction = "UP"
    if change_to == "DOWN" and snake_direction != "UP":
        snake_direction = "DOWN"
    if change_to == "LEFT" and snake_direction != "RIGHT":
        snake_direction = "LEFT"
    
    # 根据蛇的方向更新蛇的位置
    if snake_direction == "RIGHT":
        snake_pos[0] += snake_size
    if snake_direction == "UP":
        snake_pos[1] -= snake_size
    if snake_direction == "DOWN":
        snake_pos[1] += snake_size
    if snake_direction == "LEFT":
        snake_pos[0] -= snake_size
    
    # 更新游戏窗口
    window.fill(BLACK)
    for pos in snake_pos:
        pygame.draw.rect(window, GREEN, pygame.Rect(pos[0], pos[1], snake_size, snake_size))
    
    # 检测蛇是否碰到自己或窗口边界，是则游戏结束
    if snake_pos[0] < 0 or snake_pos[0] > width-10:
        game_over = True
    if snake_pos[1] < 0 or snake_pos[1] > height-10:
        game_over = True
    if snake_pos[0] == food_pos[0] and snake_pos[1] == food_pos[1]:
        score += 1
        # 生成新的食物位置
        food_pos = [random.randrange(1, (width//10)) * 10, random.randrange(1, (height//10)) * 10]
    else:
        snake_pos.pop()
    
    # 绘制食物
    pygame.draw.rect(window, WHITE, pygame.Rect(food_pos[0], food_pos[1], food_size, food_size))
    
    # 刷新游戏窗口
    pygame.display.flip()
    
    # 控制游戏更新速度
    pygame.time.Clock().tick(snake_speed)

# 游戏结束，显示分数
print("游戏结束，分数为：" + str(score))

# 退出游戏
pygame.quit()

这个程序实现了一个简单的贪吃蛇游戏。游戏窗口的大小为800x600，蛇的初始长度为3个方块，食物随机生成。玩家可以通过方向键来改变蛇的移动方向，当蛇吃到食物时，分数增加一点，并生成新的食物。当蛇碰到自己身体或窗口边界时，游戏结束，最终显示玩家的分数。

写一个贪吃蛇游戏程序可以通过使用Python编程语言来实现。下面是一个基本的贪吃蛇游戏程序的示例：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置游戏窗口的宽度和高度
window_width = 800
window_height = 600

# 创建一个窗口
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption("贪吃蛇游戏")

# 设置颜色
white = (255, 255, 255)
black = (0, 0, 0)
green = (0, 255, 0)
red = (255, 0, 0)

# 设置蛇的起始位置和大小
snake_x = window_width / 2
snake_y = window_height / 2
snake_size = 10
snake_speed = 10

# 设置蛇的移动方向，初始向右移动
snake_x_change = 0
snake_y_change = 0

# 设置食物的位置和大小
food_x = round(random.randrange(0, window_width - snake_size) / 10.0) * 10.0
food_y = round(random.randrange(0, window_height - snake_size) / 10.0) * 10.0
food_size = 10

# 设置分数
score = 0

# 设置游戏结束的标志
game_over = False

# 游戏循环
while not game_over:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                snake_x_change = -snake_speed
                snake_y_change = 0
            elif event.key == pygame.K_RIGHT:
                snake_x_change = snake_speed
                snake_y_change = 0
            elif event.key == pygame.K_UP:
                snake_y_change = -snake_speed
                snake_x_change = 0
            elif event.key == pygame.K_DOWN:
                snake_y_change = snake_speed
                snake_x_change = 0
    
    snake_x += snake_x_change
    snake_y += snake_y_change
    
    # 绘制窗口
    window.fill(black)
    pygame.draw.rect(window, green, [food_x, food_y, food_size, food_size])
    pygame.draw.rect(window, white, [snake_x, snake_y, snake_size, snake_size])
    
    # 判断蛇是否吃到了食物
    if snake_x == food_x and snake_y == food_y:
        score += 1
        food_x = round(random.randrange(0, window_width - snake_size) / 10.0) * 10.0
        food_y = round(random.randrange(0, window_height - snake_size) / 10.0) * 10.0
    
    pygame.display.update()

pygame.quit()

这是一个简单的贪吃蛇游戏程序，它使用了pygame库来创建游戏窗口，并使用基本的游戏循环来实现游戏的运行。游戏中，蛇会不断移动，当蛇碰到边界时，游戏结束。蛇可以通过键盘的上下左右键来改变移动方向。当蛇吃到食物时，分数会增加，并重新生成一个食物。游戏窗口会持续刷新来显示游戏的画面。
