It is possible to add numbers from 0-99 at the end of all line?

Hello i got something in format:

Marcin:Marcin
Pawel:Pawel

i want to add numbers between 0-99 at the end of line so result should be like:

Marcin:Marcin1
Marcin:Marcin2
..
Marcin:Marcin99
Pawel:Pawel1
Pawel:Pawel45
..
Pawel:Pawel99

etc.

Does there exist any command or plugin what can do it?

I tried manually but its so waste time, also i tried find it on google but no results.

You can run a python script within the PythonScript plugin.

If it is not yet installed, follow this guide

• Create a script (Plugins >> PythonScript >> New Script)
• Copy this code and save the file (for example insert_num.py):

import re

def insert_num(match):
    strout = ''
    maxcount = 100
    for counter in range(1, maxcount):
        strout += match.group() + str(counter)
        if counter < maxcount - 1:
            strout += "\n"
    return strout
    
editor.rereplace(r'^.+(?<!\d)$', insert_num)

• Open the file you want to modify
• Run the script (Plugins >> PythonScript >> Scripts >> insert_num)
• Done

Result for given example: (shortened)
