Question

我有使用perl编写脚本的经验，这使我可以通过使用反向标记来轻松执行linux命令。我想知道，我该怎么做这个Python？是否有一种特殊的方法来捕获命令（输出）的结果？

谢谢你：）

要添加到urschrei的答案，这是一个例子（Windows）：

>>> import subprocess
>>> p = subprocess.Popen(['ping', '192.168.111.198'], stdout=subprocess.PIPE, st
derr=subprocess.PIPE)
>>> out, err = p.communicate()
>>> print out
