使用python编写贪吃蛇小游戏

好的！下面是使用Python编写贪吃蛇小游戏的代码：

import pygame
import random

# 初始化
pygame.init()

# 游戏区域大小
width = 500
height = 500

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

# 创建窗口
screen = 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_block = 10
snake_speed = 15

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

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

# 定义蛇的移动函数
def snake(snake_block, snake_List):
    for x in snake_List:
        pygame.draw.rect(screen, black, [x[0], x[1], snake_block, snake_block])

# 游戏主函数
def gameLoop():
    game_over = False
    game_close = False

    x1 = width / 2
    y1 = height / 2

    x1_change = 0
    y1_change = 0

    snake_List = []
    Length_of_snake = 1

    foodx = round(random.randrange(0, width - snake_block) / 10.0) * 10.0
    foody = round(random.randrange(0, height - snake_block) / 10.0) * 10.0

    # 游戏循环
    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.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:

                elif event.key == pygame.K_DOWN:
                    y1_change = snake_block
                    x1_change = 0

        # 是否超出边界
        if x1 >= width or x1 < 0 or y1 >= height or y1 < 0:
            game_close = True

        x1 += x1_change
        y1 += y1_change

        screen.fill(white)
        pygame.draw.rect(screen, red, [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

        snake(snake_block, snake_List)
        pygame.display.update()

        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, width - snake_block) / 10.0) * 10.0
            foody = round(random.randrange(0, height - snake_block) / 10.0) * 10.0
            Length_of_snake += 1

        clock = pygame.time.Clock()
        clock.tick(snake_speed)

    pygame.quit()
    quit()

gameLoop()
