python生成贪吃蛇小游戏

可以使用 Python 的 Pygame 模块来生成贪吃蛇小游戏。以下是一个简单的示例代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
WINDOW_WIDTH = 640
WINDOW_HEIGHT = 480

# 贪吃蛇方块大小
BLOCK_SIZE = 20

# 颜色定义
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)

# 创建游戏窗口
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('贪吃蛇')

# 定义贪吃蛇类
class Snake:
    def __init__(self):
        self.body = [(WINDOW_WIDTH // 2, WINDOW_HEIGHT // 2)]
        self.direction = random.choice(['up', 'down', 'left', 'right'])
    
    def move(self):
        x, y = self.body[0]
        if self.direction == 'up':
            y -= BLOCK_SIZE
        elif self.direction == 'down':
            y += BLOCK_SIZE
        elif self.direction == 'left':
            x -= BLOCK_SIZE
        elif self.direction == 'right':
            x += BLOCK_SIZE
        self.body.insert(0, (x, y))
        self.body.pop()
    
    def draw(self):
        for x, y in self.body:
            pygame.draw.rect(window, GREEN, (x, y, BLOCK_SIZE, BLOCK_SIZE))

# 定义食物类
class Food:
    def __init__(self):
        self.x = random.randint(0, WINDOW_WIDTH // BLOCK_SIZE - 1) * BLOCK_SIZE
        self.y = random.randint(0, WINDOW_HEIGHT // BLOCK_SIZE - 1) * BLOCK_SIZE
    
    def draw(self):
        pygame.draw.rect(window, RED, (self.x, self.y, BLOCK_SIZE, BLOCK_SIZE))

# 创建贪吃蛇和食物对象
snake = Snake()
food = Food()

# 游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_UP and snake.direction != 'down':
                snake.direction = 'up'
            elif event.key == pygame.K_DOWN and snake.direction != 'up':
                snake.direction = 'down'
            elif event.key == pygame.K_LEFT and snake.direction != 'right':
                snake.direction = 'left'
            elif event.key == pygame.K_RIGHT and snake.direction != 'left':
                snake.direction = 'right'
    
    # 移动贪吃蛇
    snake.move()
    
    # 判断是否吃到食物
    if snake.body[0] == (food.x, food.y):
        snake.body.append(snake.body[-1])
        food = Food()
    
    # 判断游戏是否结束
    if snake.body[0][0] < 0 or snake.body[0][0] >= WINDOW_WIDTH or \
       snake.body[0][1] < 0 or snake.body[0][1] >= WINDOW_HEIGHT or \
       snake.body[0] in snake.body[1:]:
        pygame.quit()
        exit()
    
    # 绘制游戏界面
    window.fill(BLACK)
    snake.draw()
    food.draw()
    pygame.display.update()

这个代码使用 Pygame 模块创建了一个窗口，然后定义了贪吃蛇和食物两个类，通过游戏循环不断移动贪吃蛇和检测是否吃到食物，最后绘制游戏界面。
