帮我用python内置模块写一个贪食蛇代码

好的，下面是使用Python内置模块编写贪食蛇游戏的代码，代码如下：

import pygame
import time
import random
 
pygame.init()
 
white = (255, 255, 255)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)
 
display_width = 600
display_height = 400
 
dis = pygame.display.set_mode((display_width, display_height))
pygame.display.set_caption('Snake game by Pythonist')
 
clock = pygame.time.Clock()
 
snake_block = 10
snake_speed = 15
 
font_style = pygame.font.SysFont(None, 30)
 
def our_snake(snake_block, snake_list):
    for x in snake_list:
        pygame.draw.rect(dis, green, [x[0], x[1], snake_block, snake_block])
 
def message(msg, color):
    mesg = font_style.render(msg, True, color)
    dis.blit(mesg, [display_width/6, display_height/3])
 
def gameLoop(): 
    game_over = False
    game_close = False
 
    x1 = display_width / 2
    y1 = display_height / 2
 
    x1_change = 0
    y1_change = 0
     
    snake_List = []
    Length_of_snake = 1
     
    foodx = round(random.randrange(0, display_width - snake_block) / 10.0) * 10.0
    foody = round(random.randrange(0, display_height - snake_block) / 10.0) * 10.0
     
    while not game_over:

        while game_close == True:
            dis.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
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = snake_block
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -snake_block
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = snake_block
                    x1_change = 0
 
        if x1 >= display_width or x1 < 0 or y1 >= display_height or y1 < 0:
            game_close = True
         
        x1 += x1_change
        y1 += y1_change
        dis.fill(black)
         
        pygame.draw.rect(dis, blue, [foodx, foody, snake_block, snake_block])
        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
 
        our_snake(snake_block, snake_List)
        pygame.display.update()
         
        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, display_width - snake_block) / 10.0) * 10.0
            foody = round(random.randrange(0, display_height - snake_block) / 10.0) * 10.0
            Length_of_snake += 1
        
        clock.tick(snake_speed)
 
    pygame.quit()
    quit()
 
gameLoop()

这是一个基本的贪食蛇游戏代码，你可以在此基础上进行修改和优化。
