Python import commands ImportError: No module named 'commands'

ImportError: No module named ‘commands’

在Python3中执行shell脚本，想要获取其执行状态和标准输出、错误输出
的数据，遇到这个错误，原因是commands模块已经被subprocess取代了

Deprecated since version 2.6: The commands module has been removed in Python 3.0. Use the subprocess module instead.
