More efficient web framework than Web.py? Extremely Pythonic please!

Question

I love webpy, it's really quite Pythonic but I don't like having to add the url mappings and create a class, typically with just 1 function inside it. I'm interested in minimising code typing and prototyping fast.

Does anyone have any up and coming suggestions such as Bobo, Nagare, Bottle, Flask, Denied, cherrypy for a lover of webpy's good things?

What makes it a good reason?

Also I don't mind missing out (strongly) text based templating systems, I use object oriented HTML generation. Code should be able to look something like this:

def addTask(task):
    db.tasks.append({'task':task,'done':False})
    return 'Task Added'
def listTasks():
    d = doc()
    d.body.Add(Ol(id='tasks'))
    for task in db.tasks:
        taskStatus = 'notDoneTask'
        if task.done: taskStatus = 'doneTask'
        d.body.tasks.Add(Li(task.task,Class=taskStatus))
    return d

Minimalistic CherryPy is looking like a strong contender at the moment. Will there be a last minute save by another?

Answer 1

CherryPy allows you to hook up handlers in a tree instead of regexes. Where web.py might write:

urls = (
    '/', 'Index',
    '/del/(\d+)', 'Delete'
)

class Index:
    def GET(self): ...

class Delete:
    def POST(self, id): ...

The equivalent CherryPy would be:

class Delete:
    def POST(self, id): ....

class Index:
    del = Delete()
    def GET(self): ...

You can even dispense with classes entirely in CherryPy:

def delete(id): ...
def index(): ...
index.del = delete

Answer 2

I was a user of webpy. And lately, I have found django, and I think that it is great. You can just focus on your business logic and the framework will do most things for you.

Answer 3

Flask, Armin Ronacher's microframework built on top of Werkzeug, Jinja2 and good intentions (though you can use whichever templating engine you like, or none at all), does URL mapping very concisely.

@app.route("/")
def index():
  return """Hello, world. <a href="/thing/spam_eggs">Here's a thing.</a>"""

@app.route("/thing/<id>")
def show_thing(id):
  return "Now showing you thing %s."%id
  # (or:) return render_template('thing.html', id = id)

Maybe that's what you're looking for?
