python 贪吃蛇代码

我很高兴为您提供 Python 贪吃蛇代码。以下是一个简单的示例代码：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置游戏窗口的尺寸
window_width = 800
window_height = 600
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)

# 定义蛇的初始位置和大小
snake_block_size = 10
snake_speed = 30
snake_x = window_width / 2
snake_y = window_height / 2
snake_x_change = 0
snake_y_change = 0
snake_list = []
snake_length = 1

# 定义食物的初始位置
food_size = 10
food_x = round(random.randrange(0, window_width - food_size) / 10.0) * 10.0
food_y = round(random.randrange(0, window_height - food_size) / 10.0) * 10.0

# 定义蛇的移动函数
def move_snake(x, y, snake_list):
    for snake in snake_list:
        pygame.draw.rect(window, black, [snake[0], snake[1], snake_block_size, snake_block_size])

# 定义游戏结束的函数
def game_over():
    game_over_font = pygame.font.SysFont(None, 72)
    game_over_text = game_over_font.render("游戏结束", True, red)
    window.blit(game_over_text, [window_width / 2 - game_over_text.get_width() / 2, window_height / 2 - game_over_text.get_height() / 2])
    pygame.display.flip()
    pygame.time.wait(2000)
    pygame.quit()

# 游戏主循环

                snake_y_change = snake_block_size
                snake_x_change = 0

    if snake_x >= window_width or snake_x < 0 or snake_y >= window_height or snake_y < 0:
        game_over_flag = True
    
    snake_x += snake_x_change

        snake_length += 1
    clock.tick(snake_speed)

game_over()
