用Python实现贪吃蛇小游戏

好的，以下是用Python实现贪吃蛇小游戏的代码：

import pygame
import random

# 初始化
pygame.init()

# 窗口大小
win_width = 500
win_height = 500

# 创建窗口
win = pygame.display.set_mode((win_width, win_height))
pygame.display.set_caption("贪吃蛇")

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

# 蛇的属性
snake_block = 10
snake_speed = 15

# 字体
font = pygame.font.SysFont(None, 25)

# 显示得分
def show_score(score):
    score_text = font.render("Score: " + str(score), True, white)
    win.blit(score_text, [0, 0])

# 画蛇
def draw_snake(snake_block, snake_list):
    for x in snake_list:
        pygame.draw.rect(win, black, [x[0], x[1], snake_block, snake_block])

# 消息提示
def message(msg, color):
    message_text = font.render(msg, True, color)
    win.blit(message_text, [win_width/6, win_height/3])

# 游戏循环
def gameLoop():
    game_over = False
    game_close = False

    # 初始位置
    x1 = win_width / 2
    y1 = win_height / 2

    # 移动位置
    x1_change = 0       
    y1_change = 0

    # 蛇的长度
    snake_List = []
    Length_of_snake = 1

    # 食物的位置
    foodx = round(random.randrange(0, win_width - snake_block) / 10.0) * 10.0
    foody = round(random.randrange(0, win_height - snake_block) / 10.0) * 10.0

    # 游戏循环
    while not game_over:

        while game_close == True:
            win.fill(black)
            message("You Lost! Press Q-Quit or C-Play Again", red)
            show_score(Length_of_snake - 1)
            pygame.display.update()

            # 游戏结束
            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()

        # 移动蛇
        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

        # 超出边界
        if x1 >= win_width or x1 < 0 or y1 >= win_height or y1 < 0:
            game_close = True

        # 移动位置
        x1 += x1_change
        y1 += y1_change

        # 画食物
        win.fill(black)
        pygame.draw.rect(win, red, [foodx, foody, snake_block, snake_block])

        # 蛇的长度
        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]

        # 撞到身体
        for x in snake_List[:-1]:
            if x == snake_Head:
                game_close = True

        # 画蛇
        draw_snake(snake_block, snake_List)
        show_score(Length_of_snake - 1)
        pygame.display.update()

        # 吃到食物
        if x1 == foodx and y1 == foody:
            foodx = round(random.randrange(0, win_width - snake_block) / 10.0) * 10.0
            foody = round(random.randrange(0, win_height - snake_block) / 10.0) * 10.0
            Length_of_snake += 1

        # 刷新速度
        pygame.time.delay(snake_speed)

    # 退出游戏
    pygame.quit()
    quit()

# 运行游戏
gameLoop()

这段代码实现了一个简单的贪吃蛇小游戏，可以在Python编译器中直接运行。
