Convert integers to list?

Questions

I’m trying to get a list output, but I get integer results.

Is there a way to convert integers to list?

Here is my code:

list = {12, 37, 44, 96};
    list2 = IntegerDigits[list];
    Do[
     list3 = Total[list2[[i]]];
     Print[list3];
     , {i, 1, Length[list]}]
2

Do you mean this?

list3 = Total /@ list2

Yes, I meant that, thank you.

You can find this trick in Documentation of Do.

list = {12, 37, 44, 96};
list2 = IntegerDigits[list];
Reap[Do[list3 = Total[list2[[i]]];
   Sow[list3];, {i, 1, Length[list]}]][[2, 1]]

(* {3, 10, 8, 15} *)

list = {12, 37, 44, 96};
list2 = IntegerDigits[list];
t = {}; Do[list3 = Total[list2[[i]]];
 AppendTo[t, list3];, {i, 1, Length[list]}]; t

(* {3, 10, 8, 15} *)
