Considering the GP commenter started with an emphasis on concurrency, Elixir's concurrency features (thanks to the Erlang VM) are totally different than what Python can offer, namely isolated processes (scheduled in the VM so like green threads) where you can write blocking or CPU intensive code without worrying about blocking the other processes and where GC is per-process. With Python you (AFAIK) run into the GIL when threading or you fork OS processes that are heavyweight so you can't do that for every request or you'll fall down. Or you have to write async code which can still only saturate one core.

Not saying Elixir is the answer to everything but that's where it differs in the concurrency sector. It doesn't have static typing though, which is a requirement for some.
