What functional language to choose as an auxiliary language after Python'a?

Question

Python

Good day, I really wanted to dive into functional programming, I have been programming in python for more than a year, but I often hear and see that "python was not conceived as a functional language", although it has cool functionality :)
Now I am developing the server part, I would like to dig further into this direction.
In general, the question is, which functional language to choose as an auxiliary language for studying in your free time?

Answer 1

Haskell course

Answer 2

Ideologically, it would be easiest to switch to Erlang, simply because it is also strongly dynamically typed.

Answer 3

Go

Answer 4

Scala, for example. You would describe why and for what. It's just pointless to "dive" to put it mildly.

Answer 5

Common Lisp

Answer 6

For my part, I recommend Clojure . A general-purpose language with a focus on functionality.
