outfile would be a better name!

Note you haven't written anything to outfile yet; print will go to the 
console. I'm not sure what you do want to write so I won't suggest anything.

I guess this is line 16; you are closing the same file twice. Should be
   outfile.close()

It would help to see the traceback, it includes the line with the error 
so we don't have to guess which is line 16.
