I'm not really familiar with SQLObject, but are you sure file_path is
not empty?

Also, a few small comments:

1. zip is a builtin function. I would choose a different name, even
though this is not strictly necessary.

2. You can accomplish what you seem to be intending with your loop
using list.extend.

3. That's an interesting thing to put in an else case. Why did you do
it that way instead of just leaving it out?
