This is highly dependent upon your application. Maybe you can contain
everything you need to do in a single .py file and run it. Or maybe it would be
beneficial to use separate modules or packages. These aren't really
twisted-specific concerns. It's a matter of laying out your application so you
can import the code you need, where you need it. If you have all of your
Resources in a separate module or package, then you need to figure out how to
import those and hook them up to the Site object.
Extending the simple example from earlier, you might have a "run.py" in your
app:
## myapp/run.py
#
from twisted.web import server
from twisted.internet import reactor
from myapp.views import MyResource
site = server.Site(MyResource())
reactor.listenTCP(8080, site)
reactor.run()
This is highly simplified, but hopefully you can see it's just basic python.
twisted.web.server.Site needs a Resource, so you have to figure out how to
supply it. Could be in the same file, or could be importable from some other
package or module. In this case, we've decided that we'll have a views module
that contains MyResource.
A .tac file is one way to handle application startup. You could also create a
twistd plugin: https://twistedmatrix.com/documents/current/core/howto/tap.html.
Or you could have a plain old python file with reactor.run() in it. This is
prevalent in many of the howto examples and what the example above shows. I
wouldn't really worry about .tac or plugins for the time being.
At any rate, we're venturing into different territory now. You'll need to share
some code (http://sscce.org/) or give a more complete description of what
you're trying to do in order to get practical advice. It would be better to
start a new thread with a clear intent and a different subject line, unless you
still have questions about using jinja2.
