How to create cycle function in elixir

Thank you, I have 2 questions:

1. how do I use this in my code, I need it to be printed a number in my code each loop, like this:

Oh, sure. You can use Enum.zip which returns list of tuples:

posts_entries = ["a", "b", "c", "d", "e", "f", "g"]
colors = Stream.cycle(["purple", "red", "orange"])

for {el, color} <- Enum.zip(posts_entries, colors) do
  IO.puts("#{el} (#{color})")
end

2. is there a way to create this in a function?

I’m not sure what you mean exactly, but would something like this work?

def colored_posts(posts, colors) do
  Enum.zip(posts, Stream.cycle(colors))
end
