# Elixir how to iterate over two lists at once to produce a new list?

list_of_maps
|> Enum.zip(list_of_items)
|> Enum.map(fn {map, item} -> 
   if (map["b"] == "0"), do: map, else: Map.put(map, "a", item)
end)

Another way: 

for {map, item} <- Enum.zip(list_of_maps, list_of_items),
  into: [],
    do: if (map["b"] == "0"), do: map, else: %{map | "a" => item}
