Right now, if you develop something in Python, not many people complain at you, although some might say you shoulda used JS and some of them might be right....
Maybe not absolute best practice, but it's not like PHP or Ruby or Perl, where there's rarely ever any new projects everyone blogs about using them.
All the big web frameworks are still maintained, there are still new coders learning it, it's not a language that will make people be like "Oh ew, I'm not learning that language just to work on that", etc.
