No no, He is first calculating byte offsets for each line and storing
in array (that happens in loadLineOffsets function (he got that from
some stackoverflow thread).  Then he uses the offsets to quickly jump
to the required line. If I am not wrong ,  in line no 44 he is doing

            fp.seek(line_offsets[int(lineno)])

which causes off by 1 error .. If he wanted 50th line's byte offset it
is getting offset of 51st line.

I think

            fp.seek(line_offsets[int(lineno) -1 ])

is correct
