If you want the thing written out, use f1.flush() whenever you want to
make sure this happens.

If you want completely unbuffered writing, then you can open your file
this way, with f1 = open("output/test.log", 'a', 0) I think if you are
on windows you can only get unbuffered writing if you open your file
in binary mode.
