I think you are using Python 2.x, not Python 3.  So you'd better be 
explicit what encodings you want for each file.

What encoding is this file?  Since you're appending to it, you really 
need to match the pre-existing encoding, or the next program to deal 
with it is in big trouble.  So using the io.open() without the encoding= 
keyword is probably a mistake.
