使用python将文本块解析为数据库字段

Question

下面的文本块存储在一个LONGTEXT数据库字段中，需要使用python脚本将其解析到另一个表中。每个块的行数可变，顶部和底部都有不必要的文本，可以通过从结束字段减去开始字段来删除这些文本。此外，“name”在插入之前需要替换为另一个表的ID。作为python的新手，最简单的方法是什么？谢谢：-）

开始字段

show 
x1b[Kadmin@testbox> show counters
Global counters:
Elapsed time since last sampling: 304.308 seconds

--------------------------------------------------------------------------------
Total tests shown: 0
--------------------------------------------------------------------------------

x1b[2048;1Hx1b[Kx1b[?1lx1b>admin@testbox>

结束字段

show 
x1b[Kadmin@testbox> show counters
Global counters:
Elapsed time since last sampling: 304.308 seconds

name                                   value     rate
--------------------------------------------------------------------------------
packet_sent                          1234456    29305
packet_received                      1234758    29305
packet_allocated                     1234826    29288
packet_lost                                0        0
--------------------------------------------------------------------------------
Total tests shown: 4
--------------------------------------------------------------------------------
