Hello, can anybody help here..? I have a list of players and I what to delete an element, but every for loop the list is reverting to original list. See code below

list = Enum.filter(players, fn(x) ->  # Sys.Log.debug("#{x["category"]}")
                x["category"] == category
            end)

              for _ <- 1..num do
                playerMapElement = Enum.random(list)

                List.delete(list, playerMapElement)

                player
            end
