true

they are exactly the same thing, just different ways to display

>If you are trying to print the list, take a look at the options for the io:format/1 module. If you are going to be performing mathematical calculations on the different items in the list, the Erlang system will automatically treat them as numbers, because that's what they are. The issue you are seeing is due to the fact that there is no string type in Erlang, simply lists of ASCII codes corresponding to the characters and the shell makes the assumption that you have input a string, in this case. It is just a formatting issue, not a change of the underlying structure.
