Omitting results with id3reader [Beginner]

Wed Dec 5 06:43:58 EST 2007

Hey guys, hope you can help me here. I've been playing with python for
about a week or two and I've been reading "A Byte Of Python" to get me
on my feet. I've decided to write a program which will list all ID3
information in a directory of .mp3 files into a .html file.

The python script I'm using for this, along with album art (Example)
are in the same directory as the music. The output I am getting when
it reads these files is "None" so I tried to set up a way to get rid
of these results and move onto the next file.

The omitting I'm attempting is within the If statement half way down
the code, easy to find. Could anyone point me in the right direction
on how to stop these "None" results showing in the result .html file.

Thanks in advance.
