Python micro frameworks are all the rage these days
update: I’ve added bottle and werkzeug based on feedback from comments. Thanks!
It’s never been easier to setup a web app:
web.py, werkzeug and webapp have some additional features, and are considered as lightweight frameworks instead.
I prefer the url dictionnary approach (mnml, newf, webpy) to the decorator approach (juno). djng is bit different, routing is based on the django module (from django.conf.urls.defaults import url).
micro frameworks + key-value stores are a match made in heaven for webservices development.
