Looping list and add to tuple
Hello, I have a list and want to move it to map or tuple or I have a 3 map records of Repo.all, then after editing this record I want to save these to a map
[a, b, c] |> Enum.map(fn item -> item + 1 end)
now I need to save them to a map like
[a, b, c] |> Enum.map(fn item -> item + 1 end) |> ADD_TO_MAP_OR_TUPLE
how can I do this?

To produce a map, you might use Enum.into/3 directly:
[:a, :b, :c] |> Enum.into(%{}, fn item -> {item, to_string(item)} end)
#⇒ %{a: "a", b: "b", c: "c"}

You are trying to convert map to tuple with List.to_tuple/1. It obviously does not work. It works on your initial mapped data:

I am lost. It does not convert anything to the list. Please clarify what output do you expect to receive.
