I'm interested in hearing from the community about what tools you are using for building web applications in Python.
This was last asked about half a year ago (http://news.ycombinator.com/item?id=1357925) and 2 years before that (http://news.ycombinator.com/item?id=153487), but things are changing fast, especially with the recent popularity of NoSQL, so I think it's worth bringing up again.
So, what tools, databases, web servers and frameworks are you using for your latest Python web application projects? Or, if you've abandoned Python, what language have you moved to, and why?
