Why can’t I split the input with .splilines() in Python3? It returns a number of lists instead of one for each line.
I don’t know Python, so I won’t answer that part of your question, but keep in mind this puzzle is not line-based.
See for example the last choice of test 3 “Edge Cases”, that spans three lines.
in test 3 the lies after unwrap gives 2 identical choices linesInput[4] = “(Multi”;
linesInput[5] = “line|Multi”;
linesInput[6] = “line)”;
unwraped Multiline|Multiline
and the solution must be Multi ??? what am I missing
Based on the input you provided, the solution would appear to be:
Multi
line
thanks 
Hi. I passed all tests but got only 80%. I think I covered all possible cases. I use java. May I ask for any advice?
Which validator do you fail at ?
Last one, #5 More Edge Cases
Have you considered this case:
(|)
?

Nope, you got me! 
I applied this one and got 100%. Thanks a lot!
Really nice riddle… and I take it as a nice exercise for regex.
Still struggling why my nice regex in Python fails in the multiline case. (Works find for single lines and results ins nicely compact code.j)
pattern = re.compile(r’(([^)]*))’,re.MULTILINE)
It still fails for testcase03
(Multi
line|Multi
line)
Tinkering…
