Simple string.split() can do your work.简单的string.split()可以完成您的工作。
lis = string.split('Information: Device')
This will output这将输出
['',
' 1 information is displayed below Device name is ABCD Firmware version is 1.0.0 Hardware version is 1.0.0 Software version is 0.0.1 Flashed date 1-1-2020 ',
' 2 information is displayed below Device name is EFGH Firmware version is 1.0.1 Hardware version is 1.2.0 Software version is 0.0.1 Flashed date is 2.1.2020 ',
' 3 information is displayed below Device name is IJKL Firmware version is 1.0.1 Hardware version is 1.2.0 Software version is 0.0.1']
This can be now further modified as这现在可以进一步修改为
lis.remove('')
for i in range(len(lis)):
lis[i] = 'Information: Device' + lis[i]
This will output the required result, ie,这将输出所需的结果，即
['Information: Device 1 information is displayed below Device name is ABCD Firmware version is 1.0.0 Hardware version is 1.0.0 Software version is 0.0.1 Flashed date 1-1-2020 ',
'Information: Device 2 information is displayed below Device name is EFGH Firmware version is 1.0.1 Hardware version is 1.2.0 Software version is 0.0.1 Flashed date is 2.1.2020 ',
'Information: Device 3 information is displayed below Device name is IJKL Firmware version is 1.0.1 Hardware version is 1.2.0 Software version is 0.0.1']
All the list elements can now one-by-one be appended to different txt files.现在可以将所有列表元素一一附加到不同的 txt 文件中。
