>From the documentation for For: "Unless an explicit Return is used,
the value returned by For is Null."

{For[i=0,i<4,i++,{i,2 i}]}

{Null}

For[i=0;list={},i<4,i++,AppendTo[list,{i,2 i}]];list

{{0,0},{1,2},{2,4},{3,6}}

Interpolation[For[i=0;list={},i<4,i++,AppendTo[list,{i,2 i}]];list]

InterpolatingFunction[{{0,3}},<>]

Table would be much simpler

Interpolation[Table[{i,2i},{i,0,3}]]

InterpolatingFunction[{{0,3}},<>]

%==%%

True
