有效部署阿里云DDNS+Python环境
第一步复制以下代码并生成api，代码转自CSDN，并经过优化修改
请将代码保存为1.sh 然后使用sodu su 1.sh 运行代码，输入1后按回车键等待安装完成
echo "请输入序号选择你要干啥:
输入1. 升级到Python 2.7.9
输入2. 安装python3，，并与Python2共存
输入99. 直接删除python2.7和python3__危险！有可能使Yum将无法使用，知道vi /usr/bin/yum 自便

esac接下来安装requests，使用代码
sudo pip install requests
接下来去GitHub下载阿里云DDNS的py代码
