用python打个贪吃蛇游戏代码

好的，以下是使用Python实现的贪吃蛇游戏代码，需要安装pygame库才能运行：

import pygame
import random

# 初始化游戏
pygame.init()

# 游戏场景大小
screen_width = 640
screen_height = 480

# 创建游戏场景
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("Python贪吃蛇游戏")

# 游戏时钟
clock = pygame.time.Clock()

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

# 定义贪吃蛇初始位置
snake_block_size = 10
snake_speed = 15
font_style = pygame.font.SysFont(None, 30)

def message(msg, color):
    mesg = font_style.render(msg, True, color)
    screen.blit(mesg, [screen_width / 6, screen_height / 3])

def gameLoop():
    game_over = False
    game_close = False

    x1 = screen_width / 2
    y1 = screen_height / 2

    x1_change = 0
    y1_change = 0

    snake_List = []
    Length_of_snake = 1

    foodx = round(random.randrange(0, screen_width - snake_block_size) / 10.0) * 10.0
    foody = round(random.randrange(0, screen_height - snake_block_size) / 10.0) * 10.0

    while not game_over:

        while game_close == True:
            screen.fill(white)
            message("You Lost! Press Q-Quit or C-Play Again", red)
            pygame.display.update()

            for event in pygame.event.get():
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        game_over = True
                        game_close = False
                    if event.key == pygame.K_c:
                        gameLoop()

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    x1_change = -snake_block_size
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = snake_block_size
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -snake_block_size
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = snake_block_size
                    x1_change = 0

        if x1 >= screen_width or x1 < 0 or y1 >= screen_height or y1 < 0:
            game_close = True

        x1 += x1_change
        y1 += y1_change
        screen.fill(black)

        pygame.draw.rect(screen, green, [foodx, foody, snake_block_size, snake_block_size])

        snake_Head = []
        snake_Head.append(x1)
        snake_Head.append(y1)
        snake_List.append(snake_Head)
        if len(snake_List) > Length_of_snake:
            del snake_List[0]

        for x in snake_List[:-1]:
            if x == snake_Head:
                game_close = True

        for segment in snake_List:
            pygame.draw.rect(screen, white, [segment[0], segment[1], snake_block_size, snake_block_size])

        pygame.display.update()

        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, screen_width - snake_block_size) / 10.0) * 10.0
            foody = round(random.randrange(0, screen_height - snake_block_size) / 10.0) * 10.0
            Length_of_snake += 1

        clock.tick(snake_speed)

    pygame.quit()

gameLoop()
