That's an interesting question. I'd also admit that my book doesn't really focus on web development.
What I would say is that with all of the resources out there it can be tough to know what's quality. The Quick Python Book has been well reviewed from the beginning and in much the same form since the 2nd edition. So there's that testimony that it's a good resource.
The other thing is that it while it covers pretty much all of Python, it focuses on what you need to know as a developer, and has always gotten good reviews for that focus.
So I know there is a lot of stuff out there, but I think the Quick Python Book has sort of stood the
test of time as being a quality resource that covers a lot of ground, while still keeping focus on what a developer needs. :-)
