Okay, it's time for you to learn % formatting and fix this line.
Read this.
http://www.python.org/doc/2.4.1/lib/typesseq-strings.html#l2h-211
Okay, need help? Ask.
(I don't mean to be blunt, but that line is teetering on the edge of
atrocious.)

Ah. The above line here should meet the same fate. It's atrocious too.
HTH,
