Convert integers to list?

Nagon Stewart

Posted 5 years ago

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]}]

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} *)

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} *)
