How to split string after delimiter - SriRajesh - Sep-11-2019

Hi,
I have a string as below, I want to split after each "html" and extract the first string after split.
I use below code, but I can be able to split after the delimiter.

a='JKl:TOGGLE:HJAK.html:Tiger:HJA.html'
b=a.split('html')[0]

My desired output is :JKl:TOGGLE:HJAK.htm

I would just add the htm then after splitting as str.split removes the delimiter. You need to add a portion of it back. There are a number of ways to do that

>>> [f'{e}html' for e in s.split('html') if e][0]
'JKl:TOGGLE:HJAK.html'

Where is the first colon coming from as that is not in the original string?
If you want to add a colon:

>>> [f':{e}html' for e in s.split('html') if e][0]
':JKl:TOGGLE:HJAK.html'

or remove l from html

>>> [f':{e}html' for e in s.split('html') if e][0][:-1]
':JKl:TOGGLE:HJAK.htm'

NOTE: my response is using f-strings from python3.6
