main.py

def load_apps(apps):
    import importlib
    GlobalUrls = []
    for app in apps:
        module = importlib.import_module('app.{AppName}.urls'.format(AppName=app))
        GlobalUrls += getattr(module,'urls')
    return GlobalUrls

so we can access app.testapp.urls and get the list named urls in this module dynamically.

>>> from main import load_apps
>>> load_apps(['testapp'])
[('/foobar', <class 'app.testapp.handlers.RootHandler'>), ('/', <class 'app.testapp.handlers.RootHandler'>), ('/create', <class 'app.testapp.handlers.CreateHandler'>)]

and if two element in a list for load_apps function were give, it will concat the lists and return it.

This implements the django-like app url
