使用python写个贪吃蛇游戏代码

这可能需要一些编程知识，但是我可以提供一些建议：1）使用Python中的turtle模块来创建游戏窗口和蛇的视觉表示；2）设计碰撞检测算法，以确定蛇是否撞到边界或自身；3）创建一个随机食物生成器，以使蛇保持饥饿；4）实现蛇的移动功能，并增加蛇的长度以反映吃到的食物。

用Python写一个贪吃蛇游戏代码

好的，我可以为您提供一个Python写的贪吃蛇游戏代码。请注意，这是基于Python 3版本的代码。以下是代码：

import tkinter as tk
import random

class Snake(tk.Canvas):
    def __init__(self):
        super().__init__(width=600, height=620, background="black", highlightthickness=0)
        
        self.active = True
        self.snake_positions = [(100, 100), (80, 100), (60, 100)]
        self.food_position = self.set_new_food_position()
        self.score = 0
        
        self.direction = "Right"
        self.bind_all("<Key>", self.on_key_press)
        
        self.score_text = self.create_text(45, 12, text=f"Score: {self.score}", 
                                            fill="#fff", font=("TkDefaultFont", 14))
        
        self.focus_set()
        self.change_direction()
        self.mainloop()

    def on_key_press(self, event):
        new_direction = event.keysym
        all_directions = ("Up", "Down", "Left", "Right")
        opposites = ({"Up", "Down"}, {"Left", "Right"})
        
        if (new_direction in all_directions) and ({new_direction, self.direction} not in opposites):
            self.direction = new_direction
    
    def move_snake(self):
        head_x, head_y = self.snake_positions[0]
        
        if self.direction == "Left":
            new_head_position = (head_x-20, head_y)
        elif self.direction == "Right":
            new_head_position = (head_x+20, head_y)
        elif self.direction == "Up":
            new_head_position = (head_x, head_y-20)
        elif self.direction == "Down":
            new_head_position = (head_x, head_y+20)
        
        self.snake_positions = [new_head_position] + self.snake_positions[:-1]
        
        for segment, position in zip (self.find_withtag("snake"), self.snake_positions):
            self.coords(segment, position)
        
    def change_direction(self):
        if self.active:
            self.move_snake()
            self.check_collisions()
            self.check_food_collision()
            self.after(100, self.change_direction)
    
    def set_new_food_position(self):
        while True:
            x_position = random.randint(1, 29) * 20
            y_position = random.randint(3, 30) * 20
            food_position = (x_position, y_position)
            
            if food_position not in self.snake_positions:
                return food_position
            
    def check_food_collision(self):
        if self.snake_positions[0] == self.food_position:
            self.snake_positions.append(self.snake_positions[-1])
            self.create_image(*self.snake_positions[-1], image=self.snake_body, tag="snake")
            self.food_position = self.set_new_food_position()
            self.score += 10
            self.itemconfig(self.score_text, text=f"Score: {self.score}", fill="#fff")
    
    def check_collisions(self):
        head_x, head_y = self.snake_positions[0]
        body = self.snake_positions[1:]
        crosses = [position for position in body if position == (head_x, head_y)]
        
        if (head_x < 0) or (head_x > 580) or (head_y < 20) or (head_y > 600) or crosses:
            self.game_over()
    
    def game_over(self):
        self.active = False
        self.delete(tk.ALL)
        
        self.create_text(self.winfo_width()/2, self.winfo_height()/2,
                          text=f"Game Over!\nFinal Score: {self.score}", fill="#fff", font=("TkDefaultFont", 14))
        
if __name__ == "__main__":
    root = tk.Tk()
    root.title("Snake")
    
    snake_game = Snake()

这段代码将创建一个窗口，其中包含一个可移动的贪吃蛇和一个随机放置的食物。当贪吃蛇吃掉食物时，它会变得更长，并增加玩家的分数。如果贪吃蛇碰到窗口的边缘或自己的身体，则游戏结束。

好的，以下是一个简单的贪吃蛇游戏的 Python 代码：

        # 把新位置插入到贪吃蛇头部

# 定义食物类
class Food:
    def __init__(self):
        self.position = [0, 0]
        self.generate()

    def generate(self):
        # 在随机位置生成食物
        x = random.randint(0, (WINDOW_WIDTH-BLOCK_SIZE)//BLOCK_SIZE) * BLOCK_SIZE
        y = random.randint(0, (WINDOW_HEIGHT-BLOCK_SIZE)//BLOCK_SIZE) * BLOCK_SIZE
        self.position = [x, y]

    def draw(self):
        pygame.draw.rect(window, RED, [self.position[0], self.position[1], BLOCK_SIZE, BLOCK_SIZE])

# 创建贪吃蛇和食物对象

    # 移动贪吃蛇
    snake.move()

    # 绘制游戏界面
    window.fill(BLACK)
    snake.draw()
    food.draw()

    # 检测贪吃蛇是否撞到墙壁或自己身体
    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:

            quit()

    # 更新游戏窗口
    pygame.display.update()

    # 设置游戏帧率
    clock.tick(10)

运行以上代码，即可开始玩贪吃蛇游戏。
