python写一个贪吃蛇的游戏代码

好的，以下是一个简单的 Python 贪吃蛇游戏代码，希望对你有帮助：

import pygame
import random

# 初始化
pygame.init()

# 设定窗口大小和标题
win = pygame.display.set_mode((500, 500))
pygame.display.set_caption("Greedy Snake")

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

# 定义贪吃蛇和食物
snake_block = 10
snake_list = []
snake_length = 1
snake_speed = 15
snake_x = 250
snake_y = 250
food_x = round(random.randrange(0, 500 - snake_block) / 10.0) * 10.0
food_y = round(random.randrange(0, 500 - snake_block) / 10.0) * 10.0

# 定义字体
font_style = pygame.font.SysFont(None, 30)

# 定义游戏结束函数
def game_over():
    msg = font_style.render("Game Over", True, red)
    win.blit(msg, [200, 250])
    pygame.display.update()
    pygame.time.delay(2000)


# 游戏主循环
game_over_flag = False
while not game_over_flag:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over_flag = True
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                snake_x -= snake_block
            elif event.key == pygame.K_RIGHT:
                snake_x += snake_block
            elif event.key == pygame.K_UP:
                snake_y -= snake_block
            elif event.key == pygame.K_DOWN:
                snake_y += snake_block

    # 如果蛇头碰到边缘，游戏结束
    if snake_x < 0 or snake_x >= 500 or snake_y < 0 or snake_y >= 500:
        game_over()
        game_over_flag = True

    # 让蛇移动
    snake_head = []
    snake_head.append(snake_x)
    snake_head.append(snake_y)
    snake_list.append(snake_head)
    if len(snake_list) > snake_length:
        del snake_list[0]

    # 如果蛇头和身体接触，游戏结束
    for x in snake_list[:-1]:
        if x == snake_head:
            game_over()
            game_over_flag = True

    # 画出蛇和食物
    win.fill(white)
    pygame.draw.rect(win, black, [food_x, food_y, snake_block, snake_block])
    for x in snake_list:
        pygame.draw.rect(win, black, [x[0], x[1], snake_block, snake_block])
    pygame.display.update()

    # 如果蛇头和食物碰撞，分数加一且重新生成食物
    if snake_x == food_x and snake_y == food_y:
        food_x = round(random.randrange(0, 500 - snake_block) / 10.0) * 10.0
        food_y = round(random.randrange(0, 500 - snake_block) / 10.0) * 10.0
        snake_length += 1

    # 控制蛇的速度
    pygame.time.delay(snake_speed)

# 关闭游戏
pygame.quit()

还有一个笑话，为什么程序员总是那么沉迷于游戏开发？因为他们总是想把客户端和服务器端的贪吃蛇都开发了。
