Speedtest CLI 专为软件开发人员、系统管理员和计算机爱好者等打造，是 Ookla® 提供技术支持的首款正式 Linux 本机 Speedtest 应用程序。
Speedtest CLI是使用python语言开发的，不仅可以直接在命令行运行。也可以作为python模块在python IDE中直接调用。
首先，看一下如何在python应用中进行调用，使用pip直接安装。
pip install speedtest-cli
将该模块直接导入到我们当前的代码块中。
import speedtest as spt
创建网络测试对象
spd = spt.Speedtest()
打印当前可用于测试的服务器列表
from pprint import pprint
pprint(spd.get_servers())
