Python 3.x 从字符串输出中检索部分信息

我使用了一个名为paramiko的库，通过SSH连接到存储服务器，以访问各种详细信息，其中一个是服务器的硬件状态。我已经成功地将数据作为输出，我面临着解析数据以检索电源状态的困难。提取的数据是字符串格式的，我只需要一行。如果你能帮助我，我将非常感激

如果查看输出，我要检索的特定行是：

[PS0]：目前，交流良好，直流良好

注意：您在下面看到的输出都是字符串格式

   [V3]: 5.13 (Normal)
   [V4]: 12.34 (Normal)
   [V5]: 0.86 (Normal)

   [V7]: 3.17 (Normal)
Battery Information:
   Remaining capacity percentage: 92 %
   Estimated backup time:         89.1 Hours

您可以使用Regex（正则表达式）搜索特定格式并使用它。Python有as

re

模块

让上面提到的硬件状态字符串为

hardware\u status

因此，搜索模式的代码如下所示：

import re

ind_hardware_status = hardware_status.split('\n')
for status in ind_hardware_status:
    match = re.search("\s*\[PS0\]: .* AC .* DC .*$", status) # Search Pattern
    if match:
        print(match.group(0).strip())

此代码假定该行中存在交流、直流电
