Because the question is closed. Or it's open but you don't have enough reputation to answer to something that already has an answer.

Or you replied and your answer got deleted for being a duplicate. It was not a duplicate, it was the solution in python3 while the existing solution is python2.

edit: Just remember another one. That horrible time when I couldn't post the reply the OP was looking for, because the answer had to be at least 100 or 200 characters and the solution wasn't that long.
