What it offers for me truly is the batteries included and easy, memorable and predictable syntax. (Probably due to experience).
Sure, Go is easier to deploy, Erlang and by extension Elixir are easier to scale.
But python does align very well with my personal though process. I don't think parallel and I don't have race conditions in my mind. If I want to quickly write something that will perform decently, I choose python, because the time I save by not having to learn a new language could be days or perhaps even weeks. I guess it boils down to this: with my current experience, I'm more then 10 times as productive in python as I would be in any other language.
Sure, it would be neat if I had as much experience in Erlang as I have in python, but that will take years, and at the end of the day, I'd rather finish my project this year with python, then next year with any other language.
