帮我用Python 写一个贪吃蛇大作战游戏

当然可以，以下是一个简单的贪吃蛇大作战游戏的 Python 代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏窗口大小
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600

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

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

# 定义贪吃蛇类
class Snake:
    def __init__(self):
        self.body = [(WINDOW_WIDTH // 2, WINDOW_HEIGHT // 2)]
        self.direction = "right"
    
    def move(self):
        if self.direction == "right":
            new_head = (self.body[0][0] + 10, self.body[0][1])
        elif self.direction == "left":
            new_head = (self.body[0][0] - 10, self.body[0][1])
        elif self.direction == "up":
            new_head = (self.body[0][0], self.body[0][1] - 10)
        elif self.direction == "down":
            new_head = (self.body[0][0], self.body[0][1] + 10)
        self.body.insert(0, new_head)
        self.body.pop()
    
    def draw(self):
        for i, segment in enumerate(self.body):
            if i == 0:
                pygame.draw.rect(window, GREEN, (segment[0], segment[1], 10, 10))
            else:
                pygame.draw.rect(window, BLUE, (segment[0], segment[1], 10, 10))

# 定义食物类
class Food:
    def __init__(self):
        self.position = (random.randint(0, WINDOW_WIDTH // 10 - 1) * 10, random.randint(0, WINDOW_HEIGHT // 10 - 1) * 10)
    
    def draw(self):
        pygame.draw.rect(window, RED, (self.position[0], self.position[1], 10, 10))

# 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_RIGHT and snake.direction != "left":
                snake.direction = "right"
            elif event.key == pygame.K_LEFT and snake.direction != "right":
                snake.direction = "left"
            elif 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"
    
    # 移动贪吃蛇
    snake.move()
    
    # 判断是否吃到食物
    if snake.body[0] == food.position:
        snake.body.append(snake.body[-1])
        food = Food()
    
    # 绘制游戏界面
    window.fill(BLACK)
    snake.draw()
    food.draw()
    pygame.display.update()

希望这个代码能够帮到你！
