我想为下表中的每一行提取“描述”列中的字符串。由于搜索字符串包含空格，并且各列用空格分隔，所以我不确定如何解析每行中的正确字段。

似乎您的分隔符是“多个空格”。其正则表达式为\s{2,}。
因此，对于这里的每一行，description = re.split('\s{2,}', line)[-1]

我想您可以在字符串中获得每一行。
>>> s = "vmnic0 0000:3d:00.0 i40en Up Down 0 Half 00:00:00:00:03:14 1500 Intel(R) Ethernet Connection X722 for 10GbE SFP+"
>>> row = re.split(r"\s{2,}", s)
>>> description = row[-1]
