用python怎么做贪吃蛇

建议你要先拥有一个第三方库：Pygame

程序代码如下：
import pygame,sys
from pygame.locals import *
from sys import exit

class Snake(pygame.sprite.Sprite):

    snake_head=pygame.image.load('snake_head.png')
    snake_body=pygame.image.load('snake_body.png')
    snake_tail=pygame.image.load('snake_tail.png')
   
    def __init__(self,screen):
        pygame.sprite.Sprite.__init__(self)
        #蛇序列
        self.snakeLine=[(400,250),(400-40,250),(400-40*2,250)]

        #画板
        self.screen=screen

        #碰撞检测
        self.rect=Rect(400,250,40,40) #蛇头的区域

    def show(self,newSnakeLine=None):
        #将新的蛇序列设为原蛇序列
        if newSnakeLine is not None:
            self.snakeLine=newSnakeLine
            self.rect=Rect(newSnakeLine[0],(40,40))

        self.screen.blit(Snake.snake_head,self.snakeLine[0])
        self.rect=Rect(self.snakeLine[0],(40,40))

        #蛇尾
        for cord in self.snakeLine[1:-1]:
            self.screen.blit(Snake.snake_body,cord)

        #蛇尾
        self.screen.blit(Snake.snake_tail,self.snakeLine[-1])
        
    def getDirection(self):
        offX=self.snakeLine[0][0]-self.snakeLine[1][0]
        offY=self.snakeLine[0][1]-self.snakeLine[1][1]
        if (offX==30 or offX==-870) and offY==0:
            return K_RIGHT
        
        elif (offX==-30 or offX==870) and offY==0:
            return K_LEFT
        
        elif offX==0 and (offY==30 or offY==-570):
            return K_DOWN
        
        elif offX==0 and (offY==-30 or offY==570):
            return K_UP

    def move(self,KEY=None):
   
        #创建一个冲突列表
        wrong_list=[{K_RIGHT,K_RIGHT},{K_RIGHT,K_LEFT},{K_LEFT,K_LEFT},{K_UP,K_UP},{K_UP,K_DOWN},{K_DOWN,K_DOWN}]
        if KEY is None or {self.getDirection(),KEY} in wrong_list:
            KEY=self.getDirection()#按错方向键后，不改变原方向
            
        if KEY==K_RIGHT:#右移就在右侧添加蛇头，蛇尾减少1块
            self.snakeLine=[((self.snakeLine[0][0]+40)%900,self.snakeLine[0][1])]+self.snakeLine[0:-1]
            
        elif KEY==K_UP:#上移就在上侧添加蛇头，蛇尾减少1块
            self.snakeLine=[(self.snakeLine[0][0],(600+self.snakeLine[0][1]-40)%600)]+self.snakeLine[0:-1]
            
        elif KEY==K_DOWN:#下移就在下侧添加蛇头，蛇尾减少1块
            self.snakeLine=[(self.snakeLine[0][0],(self.snakeLine[0][1]+40)%600)]+self.snakeLine[0:-1]
            
        elif KEY==K_LEFT:#左移就在左侧添加蛇头，蛇尾减少1块
            self.snakeLine=[((self.snakeLine[0][0]-40+900)%900,self.snakeLine[0][1])]+self.snakeLine[0:-1]
            
        self.show()

pygame.init()

screen=pygame.display.set_mode((900,600))
pygame.display.set_caption('snake')

snake=Snake(screen)

clock=pygame.time.Clock()


while True:
   
    clock.tick(10)

    KEY=None
   
    for event in pygame.event.get():#进行事件等待
        #如果用户单击关闭窗口按钮就退出
        if event.type==QUIT:
            pygame.quit()
            exit()
        if event.type==KEYDOWN:
            KEY=event.key

    screen.fill('black')

    snake.move(KEY)

    #循环显示
    pygame.display.update()

但其中的素材你要自己找
也可以用矩形rect代替

亲测可用

谢谢

不过我这没有分

厉害呀，大神

不会啊，分数在右上角啊。
如果你觉得满意的话，能不能结个帖呢

# python实现：贪吃蛇
"""
游戏玩法：回车开始游戏；空格暂停游戏/继续游戏；方向键/wsad控制小蛇走向
"""
'''
思路：用列表存储蛇的身体；用浅色表示身体，深色背景将身体凸显出来；
蛇的移动：仔细观察，是：身体除头和尾不动、尾部消失，头部增加，所以，新添加的元素放在列表头部、删除尾部元素；
游戏结束判定策略：超出边界；触碰到自己的身体：蛇前进的下一格子为身体的一部分（即在列表中）。
'''
# 注：因为在列表中需要频繁添加和删除元素，所以用deque容器代替列表；是因为deque具有高效的插入和删除效率

        for s in snake:
            pygame.draw.rect(screen, Dark, (s[0] * Size + Line_Width, s[1] * Size + Line_Width,
                                            Size - Line_Width * 2, Size - Line_Width * 2), 0)

        # 画GameOver
        if game_over:

            if game_start:
                # print('GameOver')
                Print_Txt(screen, font2, (Screen_Width - fwidth) // 2, (Screen_Height - fheight) // 2, 'GAME OVER', Red)
        pygame.display.update()


if __name__ == '__main__':
    main()

这个也可以实现
