Web2py is fantastic. I've been using it for two years, and it is a joy. "Batteries included" is an understatement. Documentation is good, if not quite as good as Django's, the mailing list is extremely helpful, backward compatibility is excellent, and it's easy to use just the parts you like and ignore the parts you don't.

Regarding the "unpythonic" debate: Watching two years of web2py mailing list, it appears that the "OMG, new builtins and globals would confuse everyone!" fear is unjustified - I don't recall a single confusion about it (there might have been one or two I misremember - but there definitely is no room for the FUD)

If you're looking for a Python web framework, I think it is well worth your time to download and play with it a little.
