My object getting isnt working

In my game I have to do something like this but I keep getting an error for example for this one it's "Warning: one,two is not defined, defaulting to zero, in file "main" at line 10, column 11"

This is my code

init = function()
  obj = object 
    one = "apple"
    two = "pear"
  end
end

update = function()
  local objj = ["one","two"]
  print(obj[objj])
end

draw = function()
end

this is because you are trying to find a list in the object containing those but there aren't any lists in the obj so its looking for [list] but you need to iterate through each item in the list then see if the obj contains that specific item

init = function()
  obj = object 
    one = "apple"
    two = "pear"
  end
  done = 0
end

update = function()
  if done == 0 then
    done = 1
    local objj = ["one", "two"]
    for key in objj
      print(obj[key])
    end
  end
end

draw = function()
end
