用python写个贪吃蛇小程序吧

### 回答1：
好的，这是一个简单的贪吃蛇小游戏程序的示例:

import turtle
import time

# 设置窗口大小
turtle.setup(width=600, height=600)

# 创建画布
wn = turtle.Screen()
wn.title("贪吃蛇游戏")

# 创建蛇
snake = turtle.Turtle()
snake.shape("square")
snake.color("black")
snake.penup()

# 设置食物
food = turtle.Turtle()
food.shape("circle")
food.color("red")
food.penup()
food.goto(0, 100)

# 设置初始方向
snake.direction = "stop"

# 定义移动函数
def move():
    if snake.direction == "up":
        y = snake.ycor()
        snake.sety(y + 20)

    if snake.direction == "down":
        y = snake.ycor()
        snake.sety(y - 20)

    if snake.direction == "left":
        x = snake.xcor()
        snake.setx(x - 20)

    if snake.direction == "right":
        x = snake.xcor()
        snake.setx(x + 20)

# 定义按键响应函数
def go_up():
    snake.direction = "up"

def go_down():
    snake.direction = "down"

def go_left():
    snake.direction = "left"

def go_right():
    snake.direction = "right"

# 绑定按键
wn.onkeypress(go_up, "Up")
wn.onkeypress(go_down, "Down")
wn.onkeypress(go_left, "Left")
wn.onkeypress(go_right, "Right")

# 设置焦点
wn.listen()

# 游戏循环
while True:
    wn.update()

    # 判断是否吃到食物
    if snake.distance(food) < 20:
        x = snake.xcor()
        y = snake.ycor()
        food.goto(x, y)

    # 移动
    move()

    # 暂停
    time.sleep(0.1)

# 结束游戏
wn.mainloop()

请注意，这是一个简单的示例，可能需要进一步添加游戏规则、界

贪吃蛇是一款经典的游戏，我们可以使用Python语言编写一个简单的贪吃蛇小程序。下面是一个示例代码：

import pygame
import random

# 游戏窗口的大小
WINDOW_WIDTH = 800
WINDOW_HEIGHT = 600

# 贪吃蛇的尺寸和速度
SNAKE_SIZE = 20
SNAKE_SPEED = 10

# 初始化pygame和游戏窗口
pygame.init()
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("贪吃蛇游戏")

clock = pygame.time.Clock()

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

# 创建贪吃蛇
def create_snake():
    snake = [[100, 50], [90, 50], [80, 50]]
    return snake

# 创建食物
def create_food():
    food = [random.randrange(1, (WINDOW_WIDTH//SNAKE_SIZE)) * SNAKE_SIZE, 
            random.randrange(1, (WINDOW_HEIGHT//SNAKE_SIZE)) * SNAKE_SIZE]
    return food

# 游戏主循环
def game_loop():
    game_over = False
    game_quit = False
    
    snake = create_snake()
    food = create_food()
    score = 0
    
    direction = 'RIGHT'
    change_direction = direction

    while not game_quit:
        while game_over == True:
            # 游戏结束后的操作
            window.fill(WHITE)
            font = pygame.font.SysFont(None, 50)
            score_text = font.render("Score: " + str(score), True, GREEN)
            window.blit(score_text, [WINDOW_WIDTH / 2 - 75, WINDOW_HEIGHT / 2 - 50])
            game_over_text = font.render("Game Over!", True, RED)
            window.blit(game_over_text, [WINDOW_WIDTH / 2 - 100, WINDOW_HEIGHT / 2])
            pygame.display.update()
    
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_quit = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    change_direction = 'LEFT'
                elif event.key == pygame.K_RIGHT:
                    change_direction = 'RIGHT'
                elif event.key == pygame.K_UP:
                    change_direction = 'UP'
                elif event.key == pygame.K_DOWN:
                    change_direction = 'DOWN'
        
        # 判断方向是否相反
        if change_direction == 'LEFT' and direction != 'RIGHT':
            direction = change_direction
        elif change_direction == 'RIGHT' and direction != 'LEFT':
            direction = change_direction
        elif change_direction == 'UP' and direction != 'DOWN':
            direction = change_direction
        elif change_direction == 'DOWN' and direction != 'UP':
            direction = change_direction
        
        # 移动贪吃蛇
        if direction == 'LEFT':
            snake[0][0] -= SNAKE_SPEED
        elif direction == 'RIGHT':
            snake[0][0] += SNAKE_SPEED
        elif direction == 'UP':
            snake[0][1] -= SNAKE_SPEED
        elif direction == 'DOWN':
            snake[0][1] += SNAKE_SPEED
        
        # 判断是否吃到食物
        if snake[0] == food:
            score += 1
            food = create_food()
        else:
            snake.pop()
            
        # 判断游戏是否结束
        if snake[0][0] < 0 or snake[0][0] >= WINDOW_WIDTH or snake[0][1] < 0 or snake[0][1] >= WINDOW_HEIGHT:
            game_over = True
            break
        if snake[0] in snake[1:]:
            game_over = True
            break
        
        # 更新游戏窗口
        window.fill(WHITE)
        for pos in snake:
            pygame.draw.rect(window, GREEN, (pos[0], pos[1], SNAKE_SIZE, SNAKE_SIZE))
        pygame.draw.rect(window, RED, (food[0], food[1], SNAKE_SIZE, SNAKE_SIZE))
        pygame.display.update()
        clock.tick(30)
    
    pygame.quit()

# 运行游戏
game_loop()

这是一个基本的贪吃蛇游戏程序，游戏窗口的大小为800x600，贪吃蛇的尺寸和速度可以根据需要进行调整。在游戏中，玩家通过控制贪吃蛇的移动方向，尽可能地吃掉食物，并避免撞墙或撞到自己的身体。游戏结束后会显示得分和游戏结束提示。希望对你有帮助！

贪吃蛇是一种经典的游戏，可以用Python来编写一个简单的贪吃蛇小程序。

首先，我们需要导入`turtle`库来实现游戏的图形界面。然后，我们定义一个`Snake`类来表示贪吃蛇，其中包括贪吃蛇的移动、吃食物、撞墙等方法。我们还需要定义一个`Food`类来表示食物，并随机生成食物的位置。

在`Snake`类的移动方法中，我们需要通过监听键盘事件来控制贪吃蛇的方向。当贪吃蛇吃到食物时，会增加身体长度，并生成新的食物。当贪吃蛇撞到墙或自己的身体时，游戏结束。

最后，我们可以在`main`函数中创建一个`Snake`实例，并在循环中不断更新贪吃蛇的位置，同时检测游戏是否结束。

下面是一个简单的贪吃蛇小程序示例代码：

import turtle
import random

class Snake:
    def __init__(self):
        self.head = turtle.Turtle()
        self.head.shape("square")
        self.head.color("green")
        self.head.penup()
        self.direction = "stop"

    def move(self):
        if self.direction == "up":
            self.head.sety(self.head.ycor() + 20)
        elif self.direction == "down":
            self.head.sety(self.head.ycor() - 20)
        elif self.direction == "left":
            self.head.setx(self.head.xcor() - 20)
        elif self.direction == "right":
            self.head.setx(self.head.xcor() + 20)

    def go_up(self):
        self.direction = "up"

    def go_down(self):
        self.direction = "down"

    def go_left(self):
        self.direction = "left"

    def go_right(self):
        self.direction = "right"

class Food:
    def __init__(self):
        self.food = turtle.Turtle()
        self.food.shape("circle")
        self.food.color("red")
        self.food.penup()
        self.food.goto(random.randint(-280, 280), random.randint(-280, 280))

def main():
    wn = turtle.Screen()
    wn.title("贪吃蛇小游戏")
    wn.bgcolor("black")
    wn.setup(width=600, height=600)
    wn.tracer(0)

    snake = Snake()
    food = Food()

    wn.listen()
    wn.onkeypress(snake.go_up, "w")
    wn.onkeypress(snake.go_down, "s")
    wn.onkeypress(snake.go_left, "a")
    wn.onkeypress(snake.go_right, "d")

    while True:
        wn.update()

        snake.move()

        if snake.head.distance(food.food) < 20:
            food.food.goto(random.randint(-280, 280), random.randint(-280, 280))
            # 贪吃蛇身体增加的代码

        # 撞墙或自身的判断，游戏结束的代码

if __name__ == "__main__":
    main()

以上是一个简单的贪吃蛇小程序的实现，可以根据需求进行改进和优化，添加更多的功能，如计分、难度调节等。
