Python开发环境体验：2048游戏

前言

查看开发板部署了Python3.8.2的环境,可以使用python进行开发。支持python等脚本开发的话对应于很多轻量级开发场景会非常快速便捷,所以我们也简单测试下使用python 编写2048小游戏进行测试。

root@okg2l:~# python3 --version

Python 3.8.2

准备

参考https://bbs.elecfans.com/jishu_2299841_1_1.html开发环境搭建

基本的登录文件传输等操作。

2048小游戏代码

vi 2048.py

按esc按键

按键shift+:进入命令模式

输入wq!保存

运行

python3 2048.py

按键w,s,a,d回车分别对应上下左右。

总结

以一个小的程序体验下python开发的便捷,开发板支持的python版本也比较新Python3.8.2，能较好满足开发需求。
