In a lot of cases, the "performance" people care about when making language choice is "developer performance". People choosing Python feel (perhaps incorrectly) that they will be more productive and able to build things faster with that language than any of the other ones they considered.
Contrived example: If it will take you 8 hours to write something in Language A that takes 30 seconds to run, or 30 hours to write it in Language B and have it run in 15 seconds, which do you choose? If raw performance isn't the thing that's valuable to your company, maybe Language A is a better choice (even if it's slower than Language B).
