Python 贪吃蛇游戏代码示例

当然可以！以下是使用Python编写的贪吃蛇游戏示例代码：

import pygame
import random

# 游戏窗口宽度和高度
window_width = 400
window_height = 400
cell_size = 20

# 定义颜色
black = pygame.Color(0, 0, 0)
white = pygame.Color(255, 255, 255)
red = pygame.Color(255, 0, 0)
green = pygame.Color(0, 255, 0)
blue = pygame.Color(0, 0, 255)

# 初始化游戏
pygame.init()
clock = pygame.time.Clock()
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption('贪吃蛇游戏')

# 蛇类
class Snake:
    def __init__(self):
        self.head = [160, 200]  # 蛇头初始位置
        self.body = [[160, 200], [140, 200], [120, 200]]  # 蛇身初始位置
        self.direction = 'RIGHT'  # 初始向右移动的方向

    def change_direction(self, new_direction):
        if new_direction == 'RIGHT' and self.direction != 'LEFT':
            self.direction = 'RIGHT'
        if new_direction == 'LEFT' and self.direction != 'RIGHT':
            self.direction = 'LEFT'
        if new_direction == 'UP' and self.direction != 'DOWN':
            self.direction = 'UP'
        if new_direction == 'DOWN' and self.direction != 'UP':
            self.direction = 'DOWN'

    def move(self, food_position):
        if self.direction == 'RIGHT':
            self.head[0] += cell_size
        if self.direction == 'LEFT':
            self.head[0] -= cell_size
        if self.direction == 'UP':
            self.head[1] -= cell_size
        if self.direction == 'DOWN':
            self.head[1] += cell_size

        self.body.insert(0, list(self.head))

        if self.head == food_position:
            return 1
        else:
            self.body.pop()
            return 0

    def check_collision(self):
        if self.head[0] >= window_width or self.head[0] < 0 or self.head[1] >= window_height or self.head[1] < 0:
            return 1
        for block in self.body[1:]:
            if self.head == block:
                return 1
        return 0

    def draw(self, window):
        for segment in self.body:
            pygame.draw.rect(window, green, pygame.Rect(segment[0], segment[1], cell_size, cell_size))


# 食物类
class Food:
    def __init__(self):
        self.position = [random.randrange(1, (window_width // cell_size)) * cell_size,
                         random.randrange(1, (window_height // cell_size)) * cell_size]

    def draw(self, window):
        pygame.draw.rect(window, blue, pygame.Rect(self.position[0], self.position[1], cell_size, cell_size))


# 游戏主函数
def play_game():
    snake = Snake()
    food = Food()
    score = 0

    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_RIGHT:
                    snake.change_direction('RIGHT')
                if event.key == pygame.K_LEFT:
                    snake.change_direction('LEFT')
                if event.key == pygame.K_UP:
                    snake.change_direction('UP')
                if event.key == pygame.K_DOWN:
                    snake.change_direction('DOWN')

        food_collision = snake.move(food.position)
        if food_collision == 1:
            score += 1
            food = Food()

        window.fill(black)
        snake.draw(window)
        food.draw(window)
        pygame.display.flip()
        if snake.check_collision() == 1:
            break

        clock.tick(15)

    return score


# 游戏运行
while True:
    score = play_game()
    print('游戏结束！得分：', score)

    while True:
        restart = input('再玩一次？(Y/N): ')
        if restart.lower() == 'y':
            break
        elif restart.lower() == 'n':
            pygame.quit()
            quit()
        else:
            print('输入无效，请重新输入！')

请确保你已经安装了pygame库（可以使用pip install pygame进行安装）。运行以上代码后，你可以通过方向键控制蛇的移动，吃到食物后得分加一。游戏结束后，会显示得分，并询问是否再次游戏。
