写个贪吃蛇网页游戏用Python

Sure! 这里是 Python 实现的贪吃蛇网页游戏的代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏设置
width, height = 640, 480
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Snake Game")

# 定义颜色
white = (255, 255, 255)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)

# 定义蛇
snake_block_size = 10
snake_speed = 15

font_style = pygame.font.SysFont(None, 30)


def our_snake(snake_block_size, snake_list):
    for x in snake_list:
        pygame.draw.rect(screen, black, [x[0], x[1], snake_block_size, snake_block_size])


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


clock = pygame.time.Clock()

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_size) / 10.0) * 10.0
    foody = round(random.randrange(0, height - snake_block_size) / 10.0) * 10.0
    
    while not game_over:

            screen.fill(blue)
            message("You Lost! Press Q-Quit or C-Play Again", red)
            pygame.display.update()

        clock.tick(snake_speed)
    
    pygame.quit()
    quit()

gameLoop()

希望这能帮到你！
