QPlainTextEdit text and increase filename in new line in the window

问题

In my script I have a QPlainTextEdit window , when I run my pushbutton script printing a line in my window with ---projectname-seg(Segment)-group_name---, My problem is: when I run my script line is added, when I run it again is added to but I would like to increase my "Seg" in my second -def Rev_Text, each time when I run my function, like new_name change+1 each time when I run my function. I add a new line to my line_list but I can't extract last line and get only "seg element. I would like to get results lite that:

---projectname-SEG01-group_name--->1st run function
---projectname-SEG02-group_name--->2nd run
---projectname-SEG03-group_name--->3rd run etc...

That my script:

    `

Any help will be appreciated :-)
