前言

开发板具备Python运行环境，这对于一些轻量开发可以直接在开发板上进行脚本开发，这就十分方便。python --version可以看到版本是2.7.16。

[root@EASY-EAI-NANO:/]# python --version

Python 2.7.16

过程

直接SSH或者串口登录，

导入2048.py或者

直接vi编辑

添加可执行权限

chmod +x 2048.py

运行

python 2048.py

分别用wsad控制上下左右移动

总结

开发板提供了Python环境，直接开发板上进行Python开发十分便捷，这对一些轻量开发场景时非常方便。
