用python写贪吃蛇小游戏

### 回答1：
好的，以下是用 Python 写的一个简单的贪吃蛇小游戏。

import pygame, random

# 初始化 Pygame
pygame.init()

# 游戏窗口的宽度和高度
WINDOW_WIDTH = 600
WINDOW_HEIGHT = 600

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

# 设置游戏窗口
game_display = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('贪吃蛇')

# 设置时钟
clock = pygame.time.Clock()

# 蛇的大小和速度
BLOCK_SIZE = 10
SNAKE_SPEED = 20

# 字体
font = pygame.font.SysFont(None, 25)

# 定义函数，用于显示消息
def message_to_screen(msg, color):
    screen_text = font.render(msg, True, color)
    game_display.blit(screen_text, [WINDOW_WIDTH / 6, WINDOW_HEIGHT / 3])

# 定义函数，用于显示蛇
def snake(block_size, snake_list):
    for block in snake_list:
        pygame.draw.rect(game_display, GREEN, [block[0], block[1], block_size, block_size])

# 定义游戏主函数
def game_loop():
    game_exit = False
    game_over = False

    # 蛇的初始位置和长度
    lead_x = WINDOW_WIDTH / 2
    lead_y = WINDOW_HEIGHT / 2
    lead_x_change = 0
    lead_y_change = 0
    snake_list = []
    snake_length = 1

    # 随机生成食物的位置
    food_x = round(random.randrange(0, WINDOW_WIDTH - BLOCK_SIZE) / 10.0) * 10.0
    food_y = round(random.randrange(0, WINDOW_HEIGHT - BLOCK_SIZE) / 10.0) * 10.0

    while not game_exit:

            message_to_screen("游戏结束，按 Q 退出，按 C 重新开始", RED)
            pygame.display.update()

        # 处理吃到食物的情况
        if lead_x == food_x and lead_y == food_y:
            food_x = round(random.randrange(0, WINDOW_WIDTH - BLOCK_SIZE) / 10.0) * 10.0

            snake_length += 1

        # 填充游戏窗口
        game_display.fill(WHITE)

        # 绘制食物和蛇
        pygame.draw.rect(game_display, RED, [food_x, food_y, BLOCK_SIZE, BLOCK_SIZE])
        snake(BLOCK_SIZE, snake_list)

        # 更新游戏窗口
        pygame.display.update()

        # 设置游戏速度
        clock.tick(SNAKE_SPEED)

    # 退出 Pygame
    pygame.quit()
    quit()

# 开始游戏
game_loop()

希望对你有帮助！

贪吃蛇是一款非常经典的游戏，下面是使用Python编写的简单贪吃蛇游戏的代码示例。

import pygame
import random

# 初始化 pygame
pygame.init()

# 设置游戏窗口大小
screen_width, screen_height = 640, 480
screen = pygame.display.set_mode((screen_width, screen_height))

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

# 定义蛇的初始位置和大小
snake_x, snake_y = 50, 50
snake_width, snake_height = 10, 10

# 定义蛇的移动速度
snake_speed = 10
snake_x_change, snake_y_change = 0, 0

# 定义食物的初始位置和大小
food_x = random.randint(0, screen_width - 10)
food_y = random.randint(0, screen_height - 10)
food_width, food_height = 10, 10

# 定义得分
score = 0

# 游戏循环
running = True
while running:
    screen.fill(BLACK)  # 清空屏幕

    for event in pygame.event.get():
        if event.type == pygame.QUIT:  # 如果点击关闭按钮
            running = False

        if event.type == pygame.KEYDOWN:  # 如果按下键盘按键
            if 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
            elif 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

    # 移动蛇的位置
    snake_x += snake_x_change
    snake_y += snake_y_change

    # 画出蛇和食物
    pygame.draw.rect(screen, GREEN, (snake_x, snake_y, snake_width, snake_height))
    pygame.draw.rect(screen, GREEN, (food_x, food_y, food_width, food_height))

    # 检测蛇是否吃到食物
    if snake_x == food_x and snake_y == food_y:
        score += 1
        food_x = random.randint(0, screen_width - 10)
        food_y = random.randint(0, screen_height - 10)

    pygame.display.update()  # 更新屏幕

# 退出游戏
pygame.quit()

以上就是一个简单的贪吃蛇游戏的代码示例。玩家可以通过方向键控制蛇的移动方向，当蛇吃到食物时，得分会增加。游戏会不断循环，直到玩家关闭游戏窗口。希望这个示例对你有所帮助！

贪吃蛇是经典的小游戏，可以用Python来实现。以下是基本的代码示例：

import pygame
import random

# 游戏窗口的大小
width, height = 800, 600

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)

# 初始化pygame和游戏窗口
pygame.init()
window = pygame.display.set_mode((width, height))
pygame.display.set_caption("贪吃蛇小游戏")

# 定义蛇的初始位置和大小
snake_size = 20
snake_x = 100
snake_y = 50

# 定义蛇移动的速度
snake_speed = 10
snake_x_change = 0
snake_y_change = 0

# 定义食物的随机位置
food_x = round(random.randrange(0, width - snake_size) / 10.0) * 10.0
food_y = round(random.randrange(0, height - snake_size) / 10.0) * 10.0

# 游戏是否结束的标志
game_over = False

# 游戏主循环
while not game_over:
    # 通过循环遍历所有的事件
    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_size
                snake_y_change = 0
            elif event.key == pygame.K_RIGHT:
                snake_x_change = snake_size
                snake_y_change = 0
            elif event.key == pygame.K_UP:
                snake_y_change = -snake_size
                snake_x_change = 0
            elif event.key == pygame.K_DOWN:
                snake_y_change = snake_size
                snake_x_change = 0
    
    # 蛇的移动
    snake_x += snake_x_change
    snake_y += snake_y_change
    
    # 检测蛇是否碰到边界
    if snake_x >= width or snake_x < 0 or snake_y >= height or snake_y < 0:
        game_over = True
    
    # 渲染游戏窗口
    window.fill(black)
    pygame.draw.rect(window, white, [food_x, food_y, snake_size, snake_size])
    pygame.draw.rect(window, red, [snake_x, snake_y, snake_size, snake_size])
    pygame.display.update()
    
    # 检测蛇是否吃到食物
    if snake_x == food_x and snake_y == food_y:
        food_x = round(random.randrange(0, width - snake_size) / 10.0) * 10.0
        food_y = round(random.randrange(0, height - snake_size) / 10.0) * 10.0
    
    # 控制游戏的速度
    pygame.time.Clock().tick(snake_speed)

# 退出pygame
pygame.quit()

以上是用Python写贪吃蛇小游戏的代码示例，通过循环检测事件、移动蛇、检测边界和食物等，来实现一个基本的贪吃蛇游戏。游戏窗口使用pygame库来创建和渲染，控制蛇的移动和速度，判断蛇是否吃到食物，并在游戏结束后退出。这个代码示例只是贪吃蛇游戏的基本框架，你可以根据具体需求进行进一步的功能扩展和美化。
