我有使用 perl 编写脚本的经验,这使我可以通过使用反引号轻松执行 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,这里有一个示例(Windows):

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

您正在寻找subprocess模块,特别是subprocess.check_call()和/或subprocess.check_output()命令。
