File Python 3，从文件问题中提取信息

再次请求帮助。但是，在我开始之前，这里会有很多文本，所以请对此表示歉意。 在.xlsx书中，我有大约500个IP地址，设备种类为2个 我想： 远程登录设备。检查设备（通过身份验证提示）类型1或类型2

如果设备类型为1-在2x分区中获取固件版本 在excel文件中写入： 第1列-IP地址 第2列-设备类型 第3列-固件版本 第4列-保留分区中的固件版本

如果类型2-写入excel文件： 第1列-IP地址 第2列-设备类型

如果设备关闭，或设备类型3（未知）-在excel文件中写入： 第1列-IP地址 第2列-结果（EOF，超时）

我所做的：我能够远程登录到设备，检查设备类型，在excel中写入两列（在1列IP地址中，在2列中是设备类型，或EOF/超时结果） 而且，我正在将会话的完整日志以IP_ADDRESS.txt格式写入文件，以便将来进行诊断

我不明白怎么做？我不明白如何获得固件版本，并把它放在3,4列。 我无法理解如何实时处理当前日志会话，因此我决定将日志从主文件（IP_ADDRESS.txt）复制到temp.txt以处理它。 我不明白如何提取我需要的信息。 文件输出示例：

    Trying 10.40.81.167...

    Connected to 10.40.81.167.

    Escape character is '^]'.

我需要值-在“Energomera”字之后，比如2.3.1用于保留分区，2.3.1_01.04.15c用于活动分区。 我尝试过处理字符串数字和提取字符串，但没有任何好的结果

你们有什么建议或想法吗，伙计们，我该怎么做？ 非常感谢您的帮助。
