Okay so I was not able to say properly. You are indeed doing the same thing
that you were doing i.e. writting the modified data just, that now you
don't need to close you if file before doing any writting stuff. That is
there is a one line deduction from the whole code.

No. As Peter said, writing to a _new_ file is better.
Read from old, write to new, then, when you've finished, replace the old
with the new (or rename the old as a backup and then rename the new as
the old). That way, if anything goes wrong during processing, you'll
still have the original.

Good advice for those who like to butcher their data ;)
Seriously, writing modified data into a new file is the cleaner and safer
method in most cases.
