Hello everybody, Someone can explain me this result please? I have 2 list x = [“0001”, “0002”] y = [1,1] And I loop them like this: for x1 ← x do for y1<- y do IO.inspect x1 IO.inspect y1 end end But the result is like this: “0001” 1 “0001” 1 “0002” 1 “0002” 1 But I want res…

Do you mean something like Enum.zip/2 ? for {x1, y1} <- Enum.zip(x, y) do

I want this result after loop: “0001” 1 “0002” 1 but I receive: “0001” 1 “0001” 1 “0002” 1 “0002” 1 the result is multiply by 2 , but I want also one result

If Enum.zip/2 solves your problem then consider using [head | tail] notation for lists like: defmodule Example do # when done or empty input do nothing returning empty list def sample([], []), do: [] # optional code in case you have more items in one of the list # def sample([], _non_empty…

Indeed, it depends on the actual use case and what we want to return. We might also want to reach for Enum.zip_reduce/4 (for an arbitrary accumulator) or Enum.zip_with/3 (if we want to return a list). Enum.zip_reduce(x, y, :ok, fn x1, y1, _acc -> IO.puts(x1) IO.puts(y1) end)
