用python写贪吃蛇代码

好的，我可以回答这个问题。以下是 Python 语言的贪吃蛇游戏代码示例：

import pygame
from pygame.locals import *
import random

pygame.init()

# 设置游戏窗口尺寸
window_width = 480
window_height = 480
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption('贪吃蛇')

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

# 设置字体
font_style = pygame.font.SysFont(None, 30)

# 定义蛇身和食物的大小
block_size = 10

# 记录分数
def score(score):
    value = font_style.render("Score: " + str(score), True, white)
    window.blit(value, [0, 0])
    
# 画出蛇的长度
def snake(block_size, snakeList):
    for x in snakeList:
        pygame.draw.rect(window, green, [x[0], x[1], block_size, block_size])

# 提示文字
def message(msg, color):
    mesg = font_style.render(msg, True, color)
    window.blit(mesg, [window_width / 6, window_height / 3])

# 开始游戏
def gameLoop():
    game_over = False
    game_close = False
    
    # 蛇的初始位置
    x1 = window_width / 2
    y1 = window_height / 2

    # 蛇每次移动的位置
    x1_change = 0       
    y1_change = 0

    # 蛇身列表
    snakeList = []
    Length_of_snake = 1
    
    # 食物位置
    foodx = round(random.randrange(0, window_width - block_size) / 10.0) * 10.0
    foody = round(random.randrange(0, window_height - block_size) / 10.0) * 10.0
    
    while not game_over:
        
        while game_close == True:
            window.fill(black)
            message("You Lost! Q-Quit or C-Play Again", red)
            score(Length_of_snake - 1)
            
            pygame.display.update()
            
            for event in pygame.event.get():
                if event.type == KEYDOWN:
                    if event.key == K_q:
                        game_over = True
                        game_close = False
                    if event.key == K_c:
                        gameLoop()

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

        if x1 >= window_width or x1 < 0 or y1 >= window_height or y1 < 0:
            game_close = True

        x1 += x1_change
        y1 += y1_change
        window.fill(black)
        
        # 画出食物
        pygame.draw.rect(window, blue, [foodx, foody, block_size, block_size])
        
        # 生成蛇身
        snake_Head = []
        snake_Head.append(x1)
        snake_Head.append(y1)
        snakeList.append(snake_Head)
        if len(snakeList) > Length_of_snake:
            del snakeList[0]
 
        # 判断是否吃到了食物
        for eachSegment in snakeList[:-1]:
            if eachSegment == snake_Head:
                game_close = True

        # 绘制蛇身
        snake(block_size, snakeList)
        score(Length_of_snake - 1)
        pygame.display.update()

        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, window_width - block_size) / 10.0) * 10.0
            foody = round(random.randrange(0, window_height - block_size) / 10.0) * 10.0
            Length_of_snake += 1

        pygame.display.update()

    pygame.quit()
    quit()

gameLoop()

希望这可以帮到你！
