This article is divided into two parts: library installation and game production. All library commands that need to be used in the code will be placed in the first part. If the library is missing, you can go to the first part to find the corresponding commands.
library installation
1、cfg
command pip install cfg2
2、pygame
command pip install pygame

3- Snake
Here is a reference to the blogger’s great miracles, blog Python greedy snake (complete code + detailed notes + paste and eat) , for learning use only
The specific code is as follows, which can be directly copied and run without configuring background images and other front-end designs
the code
#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
#初始化蛇,长度为3,放置在屏幕左上角;
#导包

注:randint 产生的随机数区间是包含左右极限的,
也就是说左右都是闭区间的[1, n],能取到1和n。
而 randrange 产生的随机数区间只包含左极限,
也就是左闭右开的[1, n),1能取到,而n取不到。randint
产生的随机数是在指定的某个区间内的一个值,
而 randrange 产生的随机数可以设定一个步长,也就是一个间隔。
