帮我用python写贪吃蛇代码

好的，下面是一份简单的 Python 贪吃蛇代码示例：

import pygame
import random

# 初始化窗口大小、蛇、食物等信息
SIZE = 40
pygame.init()
font = pygame.font.SysFont(None, 55)


def draw_text(text, color, x, y):
    img = font.render(text, True, color)
    screen.blit(img, (x, y))


def draw_snake(snake_block, snake_List):
    for x in snake_List:
        pygame.draw.rect(screen, (255, 255, 255), [x[0], x[1], snake_block, snake_block])


def gameLoop():
    game_over = False
    game_close = False
    x1 = 250
    y1 = 250
    x1_change = 0
    y1_change = 0
    snake_List = []
    Length_of_snake = 1
    foodx = round(random.randrange(0, 600 - SIZE) / 40.0) * 40.0
    foody = round(random.randrange(0, 400 - SIZE) / 40.0) * 40.0

    while not game_over:
        while game_close == True:
            screen.fill((0, 0, 0))
            draw_text("You Lost! Press Q-Quit or C-Play Again", (255, 255, 255), 50, 200)
            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 = -SIZE
                    y1_change = 0
                elif event.key == pygame.K_RIGHT:
                    x1_change = SIZE
                    y1_change = 0
                elif event.key == pygame.K_UP:
                    y1_change = -SIZE
                    x1_change = 0
                elif event.key == pygame.K_DOWN:
                    y1_change = SIZE
                    x1_change = 0

        if x1 >= 600 or x1 < 0 or y1 >= 400 or y1 < 0:
            game_close = True
        x1 += x1_change
        y1 += y1_change
        screen.fill((0, 0, 0))
        pygame.draw.rect(screen, (255, 0, 0), [foodx, foody, SIZE, 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

        draw_snake(SIZE, snake_List)
        draw_text("Score: " + str(Length_of_snake - 1), (255, 255, 255), 10, 10)
        pygame.display.update()

        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, 600 - SIZE) / 40.0) * 40.0
            foody = round(random.randrange(0, 400 - SIZE) / 40.0) * 40.0
            Length_of_snake += 1

        clock.tick(10)

    pygame.quit()
    quit()


clock = pygame.time.Clock()
screen = pygame.display.set_mode((600, 400))
pygame.display.set_caption("Snake game")
gameLoop()
