python - How do I write a single-file Django application?

Question

I want to write a very small Django application in a single file, requiring all the appropriate modules and stuff, and then be able to run that as a normal Python script, like this:

$ python myapp.py

You can assume I won't render HTML, so I don't need templates (I'll return JSON or some other auto-generated string).

Getting started with Django can be pretty easy too. Here's a 10-line single-file Django webapp:

import os
from django.conf.urls.defaults import patterns
from django.http import HttpResponse
filepath, extension = os.path.splitext(__file__)
ROOT_URLCONF = os.path.basename(filepath)

def yoohoo(request):
    return HttpResponse('Yoohoo!')

urlpatterns = patterns('', (r'^hello/$', yoohoo))
